Title: Welcome to The Tube-O-Phile Circle
Post by: JakeJ on 26 Mar 2009, 08:29 am
Hello and welcome fellow tube-o-philiacs,

I’m sorry to be a bit late in rolling out the welcome mat but I see it hasn’t stopped anyone and that’s great!  That’s kind of a rule of thumb when visitors come to my home, if you want something then speak up, or just help yourself.

This Circle is for those who love tubes, their soft glow, and their wonderful sound.  Please feel free to spout off about your tube-based gear and system.  Show us the new (and old) tube gear you own or just bought.  Got a Nixie tube clock?  Tell us where you got it (or how you made it) and how much it costs, someone else may want one too.  If it's electronic and got a bottle in it we want to know and see!

Circuit topology discussions, kits and their manufacturers, tube choices and sonic comparisons are all welcome.  Solid state rectification and voltage regulation allowed.  DIY is also allowed but if you already started in The Lab then feel free to place a cross reference link here, and vice versa.  Please, ladies and gentlemen, no arguments about tubes vs. solid-state, both have a place in our audio universe and I own both.

Have a thermionically enhanced day,
JakeJ

Recently acquired my first tube integrated. Its a Rogue Cronus. I am still in the honeymoon phase but I will be looking for slightly brighter preamp tubes in the future I think. The unit uses 3 12AU7 and 2 12AX7. for the 12AX7 I am thinking about the LPS because I have enjoyed it as a preamp tube in the past. Any suggestions for 12au7 woud be appreciated. The stock are EH and as I said before, I am loving the unit to death so nothing will get swapped out soon. The mids on this unit are like liquid gold.

Title: Three for the Circle_the Linestage & Phonostage......
Post by: Hank Murrow on 19 Apr 2010, 07:29 pm

(http://www.audiocircle.com/image.php?id=29213)

A custom Linestage built for me by Paul Birkeland employing I.A.G. Transformer Volume Controls (Sowter/Shallco "C" series 27 position switch) at the input, and has a hybrid shunt-regulated power supply using EL84 tubes as current sources supplying 6C45Pi tubes which are coupled with TFTF V-caps to MagneQuest B7 all-Cobalt output transformers in  parallel-feed.

(http://www.audiocircle.com/image.php?id=29221)




(http://www.audiocircle.com/image.php?id=29218)

The Phonostage, using the “Eros” circuit designed by Paul Joppa of Bottlehead; with one stage added for slightly more gain and lower output impedance.

(http://www.audiocircle.com/image.php?id=29219)

The signal side is an EF86 directly coupled to a 6922. The 6922 is cap coupled with a TFTF V-cap to a 6C4 transformer coupled voltage amplifier, which is coupled via another TFTF Vcap to the 125 ohm center tap of the Magnequest Nickel B7. This arrangement is ideal to drive the low- impedance TVC's in the linestage. The dual hybrid shunt-regulated power supply in the left box uses 6X5 rectifiers and 6S4 tubes as regulators.


(http://www.audiocircle.com/image.php?id=29220)

The octal sockets accommodate Peerless 4722 step up transformers for low output moving coils. When the 4722s are inserted, the MC inputs are used. If MM cartridge or hi-output MC is used, the 4722s are removed.






Title: The third custom piece by Paul Birkeland: the 2A3 Amp......

MQ 15335 input transformer at left, MQ filament choke for the 2A3. 6CK5 driver loaded with current source, MQ BCP-16 Cobalt grid choke for the 2A3, MQ EXO-03 plate choke for the 2A3, and 6 uf parafeed oiler near the output taps.

Completely separate Power Supplies for each channel with BH PT-5 transformers feeding separate hybrid shunt-regulated power supplies with 6S4A’s operating in the hybrid regulator circuit. Amp weighs in @ 47 pounds & needs the fan!

(http://www.audiocircle.com/image.php?id=29225)

Top detail: 6CK5 driver tube, CuTf V-cap, 2A3 output tube, TFA 2004 Jr. M6/Cobalt parafeed transformers, and Pyramid 6uf oiler parafeed caps.
The whole system is dead quiet, has great dynamics & drive, and gets me back to my huge mint vinyl collection again.

Cheers, Hank

Well I guess I can join the circle since I just became Tube-O-Phile!!

Received my entry level Amp 4 days ago and in the process of burning in the tubes, I have about 40 hours, manual says 100.

Wanted to get my feet wet with tube sound, but, unfortunately, I'm DROWNING in pure unadulterated presentation of clean music. My ears are at the point of no return!!!!

I don't think I have ever heard " music sing " like I am hearing with this amp!!!

All I can say is WOW....loving it!!!

Actually there is a Critic's Circle where reviews belong but you sure can put a link to it in this circle.  Tried to see what else you are using for associated gear but your system is just a 20 x 24 room.  ;)

The Tube-O-Phile Circle is for discussion of gear, tube rolling, projects, Brand X vs. Brand Y and just about everything else tube related except reviews.  That might be confusing because not all reviews are in the Critic's Circle but most of them are in manufacturer's circles which is understandable.

Hope you understand.

Wrong room, Jake, that is the theater room!

The designated 2 channel listen area room is  11x12 and where the Tube amp is. The reason to post here was to discuss tube amps/tubes and get a better understanding of them and how they work. And of course to show off my tube amp and get some opinions.

I also have pics and review URL!!!

Uploading pics of my new almost broke-in Yaqin MS-20L Integrated Vacuum Tube Amp an upgrade from the 10L with great features for a 'high end entry level' Tube Amp. 50 wpc, UL and TR switchable, remote, and positively super quiet!!!Really enjoying this amp.

With 4 EL34B and 8 6J1s to be exchanged with 8- 5654W/6AK5WBs very soon.

From Canadian HiFi at 600.00 (delivered) through Ebay, with QC in Canada great customer service and fast delivery it is a winner with me and I am proud to be a 'Tubey'....

Maybe to the point of no return!!! :scratch:


Without the EL34Bs.

Hey Jake,

Rolling out the 8 -6J1s in the front of the amp (have El34s in back (4) of them), and I am changing the front ones to GE 5654Ws NOS/NIB.

In the 20L manual it says use match pairs or quads. These are just 8 matched ones. Am I ok with this?

Thanks,
Rob

Rob,

I couldn't find the manual online but if you have eight of the same tube type and they are all matched then you should be good to go.  Please let us know what you think after listening for a while.

Jake,

Just flipped the switch and checked email. Wow the sound is different, but I will give a report after break-in.

Problem is I just got 2 new WAF-1 speakers, so I am breaking them in too.

Listened to the last half of  'Just You and Me'' by Chicago and The Search of Over' by Survivor' More open, airy and bigger sound stage so far. Really different than the 6J1s and they weren't bad.

So, let's let them break in.

Thanks,
Rob

Hi Tube Nuts,

I haven't really been "into H-FI" for a very long time having considered myself more of a music guy.  Early on I was using an old Voice of Music integrated tube amp that someone had given my father years earlier to settle a debt.  Along with it was an old Fisher tube tuner.  The tuner channel was the only one that worked in the amp and I didn't know the first thing about how to restore it. But mostly over the years I've had mid-fi and speakers I could crudely construct.  That all changed just over 2 years ago when I fell into tubes in a big way.

http://www.carveraudio.com/phpBB3/viewtopic.php?f=31&t=5691&start=45 (http://www.carveraudio.com/phpBB3/viewtopic.php?f=31&t=5691&start=45)

Now I love them so much it's hard to see myself without them.  You could say I've been converted.



Glad to meet you all.

cheers,  weitrhino

Post by: woodsart on 29 Oct 2010, 05:13 pm
Yeah, weitrhino, the same with me, been a long time since I really sat down to listen to music, until now.

Got into the surround first, then began reading about 2 channel and that seemed to be the biggie.

Even at RMAF, a lot of tubes were lighting up the rooms, so I heard and so it looked in the pics.

And, with my little Yaqin, I am in love :hyper:!!!

Amazing how Pandora One is with Tubes too!

Getting ready to move the speaks I have with the amp in the theater, so I will be looking for 2 more. So much more fun with tubes.

Also I am considering a new sound card, it is called the Asus Xonar PCIe Sound Card. Suppose to have Burr-Brown codecs. Anyone heard of it?

Thanks,
Rob

Hi All,
My first post here.
I have had a pair of Anthony Gallo Ref AVs as my bedroom setup for 2 years.
Since these speakers are really power hungry I had to go with powerful SS Amps and so I bought the
Denson B-200 Pre & B-320 Power.
Very, very transparent, great resolution and speed, BUT VERY bright & cold. 
Was not happy with the brightness in particular
Since there is no exchange policy here in Dubai, I was stuck with it.
Replacing the Densons with a high end Prima Luna tube amp was an expensive option and I am a married man

A few month ago I came across the MHDT Havana Tube DAC and decided to give it a try. 
I got it a month ago and the difference is phenominal.
The brightness is gone, soundstage has widened, bass has tightened and the mids are to die for.
WOW...
I did'nt know that a pair of tubes could do so much...
Regards

Mind if I pull up a chair and have a listen ?
I have a pair of BLH in need of a amp. They are the Dallas II design with Fostex FE206E drivers. I was using a Nakamichi TA-2A 50Wx2 stasis receiver but it was hit by lightning. I have a chepo T amp on the way from PE but am trying to learn all I can about tube amps.
I'm jealous of weitrhino for wining a Carver tube amp. Have you got it yet dude ? Will you post pics or do you have a superior moral justification for your selfishness ?

I'm back in the wonderful world of tube after being away from home audio as a whole for 8 years.  I have a Yaquin MC-10L and MS-22B currently and I am pleasantly surprised by the sound quality.  The MS-22B is highly modified and the MC-10L is in the process of getting component upgrades.  I do hope to build a Audio Note Kits Legend 300B parallel SET over the winter.

While totally immersed in the hobby years ago I've owned:

ASL Tulip 2A3
Quicksilver KT88 Monos
A EL84 based Jolida that I can't remember the name of

Newer to AC and in the process of putting together a dedicated 2-channel listening room (build out under way including room treatment).  I have some great SS stuff for other locations in the house but really LOVE the sound and beauty of tube gear.  Primarily will be using my Mastersound Dueventi (integrated) with digital front-end and a variety of higher efficiency speakers.  Backup is a custom EL84 based parallel pentode amp for some variety in life.  I have been gradually accumulating a variety of NOS tubes for both amps (EL34, EL84 for output and 12AU7's for input) but the EL34's are really getting expensive.  Decided to acquire a small stash of NOS tubes before the situation invariably worsens.  Attached is a stock photo of the Mastersound but will upload photos of the room and gear when done.  Regards.

So glad to find the Circle and the tube aficionados. I will soon have a modified ST70 Dynaco I will feed from a Schitt DAC, a turn table and old PAT4 preamp as needed. I really like using both analog and digital... I use my Hasselblad w/film and edit/print the scans digitally. Best of both worlds.

I'm contemplating building GR XLS speakers. Question: will 35 wpc be ok for moderate listening levels in a small room? A good sonic match?

Thank you,.

Hey!

   Welcome to the Audio Circle and especially to the tube circle. I think you probably the first one to mentioned tube and Hasselblad film camera together on the first post, that's cool man  8)

   Well, I'm running SET amps with Fostex 6" single driver speaker and I have Hassy 500C/Ms with 50mm f4 T*, 80mm f2.8 T*, 150mm f4 all chrome and 3 120 backs. Mostly B&W, I can't seem to get B&W from my current digital cam Sony A7II the same way I get from film still.

   Anyway, I'm not familiar with the speaker you've mentioned, but I'm sure someone here can comment on that one. Selecting speaker is not easy, you have to factor in how big is your room, how loud you listen, and of course how is your budget.

Buddy

Shouldn't be a problem at all. Don't know what modified ST 70 you have, but modern versions of the ST70 like the AVA Ultravalve and Latino sound much stronger than their 35-40 watt ratings. The GR speaker mentioned looks to have typical tube friendly specs for a small 2-way as well.

Sadly, I just sent my Sonic Frontiers Power 2 off for service. Hope it's well. I bought a MHDT Orchid tube DAC today. Figure my analog playback is tube (Sonic Frontiers phono stage) so getting more tubes is good. Funny to see people mentioning Hasselblad since I also shoot with a Hassy. Print in a color darkroom. Also shoot with a 4x5 view camera (Ebony) so I guess that explains my preferences.

Ok thanks! I was also considering Gold Lion KT77!

I know it's very subjective assessing tubes, but I switched from stock Primaluna EL34 to Gold Lion KT77 (in an Evo 300 Integrated) and I'm quite happy with them. Definitely worth a try, IMO.

Hello,
I am a tube audiophile from way back. I built my own many years ago.
Now there are so many excellent tube amps, kit building seems almost pointless.
I am also a fan of tube rolling. Currently trying some NOS RCA Clear Tops in my preamp section.
Very nice so far.

Wouldn't be surprised if you find them bright in the long term.  That's been my experience every single time I've tried them, no matter the gear.

Hello and welcome fellow tube-o-philiacs,

I’m sorry to be a bit late in rolling out the welcome mat but I see it hasn’t stopped anyone and that’s great!  That’s kind of a rule of thumb when visitors come to my home, if you want something then speak up, or just help yourself.

This Circle is for those who love tubes, their soft glow, and their wonderful sound.  Please feel free to spout off about your tube-based gear and system.  Show us the new (and old) tube gear you own or just bought.  Got a Nixie tube clock?  Tell us where you got it (or how you made it) and how much it costs, someone else may want one too.  If it's electronic and got a bottle in it we want to know and see!

Circuit topology discussions, kits and their manufacturers, tube choices and sonic comparisons are all welcome.  Solid state rectification and voltage regulation allowed.  DIY is also allowed but if you already started in The Lab then feel free to place a cross reference link here, and vice versa.  Please, ladies and gentlemen, no arguments about tubes vs. solid-state, both have a place in our audio universe and I own both.

Have a thermionically enhanced day,
JakeJ

Hello, I am brand new here and wish to start educating myself on tube type equipment.
I just got a VTL pre-amplifier and amplifier and have a lot of questions about the equipment.
Is VTL still in business and I have an amplifier that has a dead channel with a blown fuse.
Thanks

Greetings all! Noob to the forum over here. My gateway drug was a Little Dot MKIII (lowest gain setting to avoid clipping, used as a pre-amp into the CD input of my integrated amp) and the GREAT "Little Dot MKIII tube rolling" thread over at headFi.org. Thats where I first learned about how to pick different tubes that might appeal to me. And it was on  :lol: After obsessing a lot over tube minutiae, and learning about how to research, buy and listen to the different things that the little dot could do with tube rolling, I got some Rogue audio gear, (more obsession and research and rolling) and the current set up is a Don Sachs Pre-Amp and a Cary Audio CAD120 MKII-S. I can't imagine ever having a Non-tube system any more. Im really glad to find a bunch of fellow tube nerds. And I could talk for DAYS about this pre-amp. Its incredible.

Love this site!
After spending years lost in SS, I started missing the tubes. I kind of jumped the gun this time and forgot how I love the EL34, and picked up a KT88 power amp to mate with my old Audio Mirror T-61. While I am burning in a quad of KT77 (I just could not get into the 88/90 sound), I am close to purchasing a few other tube type amps (300B, 845, etc.). I think I can pull it off as my wife sees all my gear as either silver or black metal boxes...
Sorry, my name is Michael, I'm from the US and love purchases that I can mod/need some TLC. I just finished a set of Devore clones with the help of HumbleHomeHiFIs Tony Gee and am burnt out on speaker tweaking for a bit, so it's back to something with tubes...

Welcome to AudioCircle, Michael!

Tony is very talented. I'm working on a speaker like that too, inspired by his Plutone.

I am new to the group but have had a Audiopax Model 88 tube monoblocks for about 20 years.  They are unique because they use KT88s but output in triode mode.  Very wonderful sounding and a great match for the Avantgarde Duo horn speakers.  I am looking at changing out the KT88s (4 total) and wonder what others are using and what you recommend for a quality 88.  I am using Mullard 12AT7 NOS for the drivers and love them - don't plan to change them - but the current 88s have probably 3000 hours on them and are ready to go!

Welcome to AudioCircle, MAS
I've used Gold Lion KT-88s with good results in Audio Research amp. Nice sound, and reliable. Jim McShane is a good source for NewSensor tubes.

Jim McShane is out of GL KT88s, I believe he still has some EH KT88s.

just bought my first piece of tube equipment since  college back in the 80's.  Raven Blackhawk 20w integrated.  Love the sound but I'm driving very inefficient speakers (b&w 802 series 80).  considering Reference 3A de capo BE.  thoughts?

Once again the question is, room size, music choices and listening levels? The 3A's would be excellent for an average sized room at decent but not outrageous listening levels. Add a REL or similar sub or 2 if necessary. For larger rooms at even higher vol. levels, 4th generation Klipsch Heritage starting with the Heresy 4, Tekton Lore's or new ZU DW 6's..... or something more upscale in any of their lineups if needed.

Dude,

I knew I couldn't be the only audiophool in Corvallis.  :thumb: I'll send you a PM if I can. You may need to post two more times before anyone can PM you. [Edit: I just noticed you included an email link.]

New to this circle and to AudioCircle.  I listen primarily to vinyl and primarily to tubes. A Dodd Audio phono stage was my introduction to tubes years ago. I stumbled onto Decware amps in 2018 or so, and have never looked back. In addition to the Dodd, I’m currently running Decware Se84UFO25, ZMA, Torii Mk IV, SE84UFO, ZP3, ZRock2, and ZBox in various systems. I’ve been on the waiting list for a Sarah for 7 months, with another 2+ years to go. I suspect. In the meantime, I keep pondering Dennis Had and Will Vincent gear despite having no conceivable place to put it. As with most folks, I tend to think my taste in music is pretty wide ranging; whether that’s quantitatively true or not, who can say.

You might also check out the Kenny Russell offerings at www.getdynaco.com. This especially if you're fond of EL84 based amps. His "new" ST-35 build is superb and "supposedly" tops the little 2 or 3 watt Decware Zen with ease. Now before you shoot the messenger, this is according to drD E, an audio reviewer you can find on YouTube. He has or had both amps in house and if nothing else, he retained the ST35.
