Back in the 45 family again :green: This 45 SET is a mix of old and new. The amp is based on the KORNEFF circuit (built by Oliver Sayes) using iron from Hashimoto (h-507s). My 1st SET using Hashimoto iron. :thumb: The drivers are 6p5 and powered by a 5y4. I have attached a couple pics for your viewing pleasure..
Enjoy

Is that brand new? I have a 421a amp from Oliver and it uses the Hashimoto HC-203U (http://jelabs.blogspot.com/2013/12/hashimoto-hc-203u-se-output-transformer.html) transformer, which is a modern day improved version of the Tango U808. Its not potted or as pretty as yours though. My amp is based on Don Garber's Fi 421a and uses Jensen capacitors instead of the sweet Jupiters you have. But Oliver leaves a lot of space under the hood so there is room to replace them if I want. It uses a 6SL7 (or 6SN7) and a 5Y4 (or 5Y3) rectifier and a 5998 or WE 421a tube. Nice 4wpc.
-
yep it's new
-
Oliver has done a number of these based on that circuit. He likes to use vintage Tamura output transformers from old Sony RTR machines. Not the best bass in the world, but sometimes smaller transformers can have a magic the big iron doesn't.
I like the old single triode driver tubes. I have a preamp that uses 27 or56 tubes. I'm guessing with the 6p5 driver tubes this amp really needs a preamp to get full power out of the 45's.
-
Very nice Dwight. I just replaced Exotica TFT caps with Jupiter caps in my 45 amp.
-
The HC-203's were my 1st choice but would not fit...I agree that 'Less is More'. I debated on using an Oil based over the Jupiter's. I have used Jupiter Cu's in my MHDT DAC with positive results. 6p5 use all the gain from my 14db tube preamp. :green:
thank you roscoe65 / mothaudio for your comments and insight :thumb:

I was envious of your outputs until your comment: I thought they were the H-20 at first. Yours are pretty small. But with the 45 that isn't much of a problem since the higher impedance give you greater inductance.
My H203's are a "cost down" version of the H20. End bells instead of potted and flying leads instead of terminals. It also has a slightly different core which results in slightly lower inductance. They were already installed when I bought the amp (Oliver had it in his system at the time. I was inquiring about a 2A3 amp he was selling and he offered this as an alternative). I believe that Don Garber now uses the H-20's in his Fi 421A, replacing the Magnequest DS-025's he originally used. I had a pair of DS-50's about 20 years ago that I was going to use for a 4 amp. The Hashimoto's are a bit larger and of equal or better quality.
-
I live right near oliver. I have the luxury of hearing a lot of his work before it leaves. He has a 26->46 from his system he is considering selling. It sounds glorious. 1.5Ws won't work for me (and I already have a 10Y to a 300B made with Slagle iron). I think is all vintage tango iron. Someone is going to be very lucky to own that amp. Anyway, we spent some time listening to Slagle Iron vs tango at one point. We didn't have Hashimoto to listen to at the time. Would have been a fun time to listen to it all. I must say if you can get away with 1.5W, the 46 is amazing. Sounds better than a 45 to me.

I remember talking with Oliver about a similar amp - he was looking for more money than I could justify for a flea power amp. Justifiable, given the PS challenges of DHT drivers, but not in my budget.

Yes. Cost is hard. That said, I find myself (in the past, not now), wishing I had spent more on the amp and less on the tubes. Properly designed, swithing the tubes is like tuning the amp a bit. The iron does what you want it to and gives you that awesome tone. The tubes refine it. My 300B collaboration with Oliver has some mild changes with different 300Bs and 10s, but nothing as significant as changes in out put iron or the like. We listened to a 10Y-->300B with Tango iron and with Slagle iron side by side. Same tubes. Were there differences? Absolutely. Was it big? Not at all. Kind of a neat experience.

Can you please elaborate a bit on the differences heard between the Tango and Slagle iron? Were the two OPT's similar in size, load impedance and wattage?

Wow great FR line array speakers, I though they had only the Robin, its site is odd to surf.
How they sound w/only 2W?
-
6p5 provides enough gain to get the job done but I could always use the 6j5 if more is needed. The Raven's are 96db which is workable with the 45. I also broke down and had a custom stand made..having your set amp on da floor is silly

Agree. I cringe whenever I see expensive tubes exposed sitting on the floor like that. Plus I admit, as a visual artist, I enjoy the view too much to have them down low.

That would have to be tested in an identical circuit. There are transformer shootouts from time to time (the most recent I've seen is a budget transformer shootout over at JELabs between Edcor and Noguchi transformers) but not as frequently as there were about 20 years ago or so, when SET's were mostly DIYor custom. The problem is that a real shootout of all or most available transformers would require us to have $5,000 of iron available to swap into a circuit.
Given a reputable hand winder and the materials and tech that are accepted to perform well, it becomes a matter of choice. Your Electraprint iron is of good reputation but does fall into the lower (but not lowest) price range. One advantage of EP iron is like many US manufacturers you can specify exactly the iron you would like within the confines of their factory capabilities. The partial silver secondaries seem to be a particular bargain.
20 years ago we could choose from the big Japanese names (Tango, Tamura, etc.), Audio Note, Bartilucci, Magnequest, Lundahl, Electraprint, and some custom options available from Cary (Audio Electronics Supply - probably Edcor), Edcor and a handful of others. Today, Tango is gone (RIP 2013), AES no longer exists, but we have access to a large Chinese manufacturing sector (for better or worse) and newer players have come on the scene, such as James (Taiwan) and the renewed availability of Hashimoto/Sansui (Japan). We can pick almost any price point and specification from $50 to $750 for the typical 2A3/300B transformer.
Personally I like Hashimoto, but Shindo uses Lundahl and others like Wavelength use Magnequest. Decware uses Edcor (I think) and Fi has switched from Magnequest to Hashimoto.
But to speak more directly to your question, this test hints at the relative quality of Electraprint: http://www.meta-gizmo.org/Tri/vtv-se.html

Thanks Roscoe. VTV, miss those guys.
I have always been on the fringes of the SET movement, but have been involved since the mid 1990's. I'm not sure how I found out about it but was a subscriber to Sound Practices and am still on the Joelist email blast. The Sound Practices guys have stayed in the game, and some can be found in mainstream publications (Herb Reichert) but most are on some of the other, older forums online.
-
It is hard to describe the difference. First, the iron was rated at the same impedance, but I did not think to ensure the. The tango was XE-20s at 5k. Slagle was iron good for 10 watts on nickel core. Both were awesome. I would say slagle's was more transparent, while the tango had slightly better top end extension and realism. Hard to characterize it.
-
I have not been here for a while... your system appears to have undergone a few changes. Looking good!
That amp looks like a well-executed traditional-style build; clean. Should provide years of enjoyment.
Cheers.

Roscoe,
I'm thinking of ordering Oliver's SE 46 amp and have allocated a budget of 3k for this custom amp. I need some help in deciding what transformers to use for the output. Oliver has suggested either the Tango/Hashimoto or the Dave Slagle nickel. My friend have suggested why not Lundahl? The sound that I'm striving for in this amp is sweet but crystalline highs, a balanced and neutral midrange and clear and deep bass. What is your recommendation on output transformers? To put things in perspective this amp will be replacing a Decware SE84UFO2 that I've had for awhile now but I've heard some good things about the 45 and 46 tubes and I think I have the right speakers for them. Hopefully I can get some clarity here. Thanks in advance.
Kevin
-
Tango/Hashimoto usually use small core=low power handling. Not sure if this is relevant on a flea power 45.
-
The cost of the tango iron is near the top end of your budget. Tango stuff has gone over the moon of late. Lu Dahl output iron is not impressive to me. Slagle and tango are close. Tango is tracking more expensive than slagle right now.
-
Tango =/= Hashimoto.
I can't comment directly on the Tango vs, Slagle comparison.
The Hashimoto transformers are excellent. I have a pair of H203U' sin my 421A amp. This is the spiritual successor to the old Tango U808 "universal" transformer. I recall a comparison in Sound Practices about 25 years ago with this transformer. At that time they preferred most other transformers, including the Magnequest DS-025 and especially the FS-030. However, Joe Esmilla vastly preferred the Hashimoto to the Tango.
For what it's worth, Don Garber has been using Magnequest iron forever, but has somewhat recently switched to Hashimoto. The pricing is comparable so I would have to assume that it is a performance factor.
My personal recommendation is to ask for Oliver's opinion. He has had a lot of experience with this circuit and if you convey what is musically important to you the two of you can probably arrive at a choice that will make you happy.
-
The 80% nickel Slagle iron are wonderful, also they can be regapped to suit your amp, sometime text book formula may not be the best for every system.
the Tango U808 is musical but not in the same league as the Tango Permalloy or the Slagle nickel.
If someone wants a pair of Tango U808 I have a pair available!
-
I use the slagle nickel in my 300B amp. oliver has Tango. They are very close. The Tango Oliver using had about 10 years use when we listened. Slagle iron had about 10 hours. IMHO Parts of the Tango presentation of the upper midrange were better. Low end and highs better on Slagle iron. YMMV. Also, the B+ On the Slaglewas lower at the time. Not sure that had an effect. Switch error. (My amp will run 300B, 275A and 6A3 tubes).
-
Thanks for all of the feedback guys. Well I guess it comes down to Tango, Hashimoto, or Slagle nickel. Interesting that these are the 3 choices that Oliver offered me. I"ll email him and finalize my decision based on his circuit and my musical tastes.

Happyrabbit,
I can't agree more with your description of the 45.
I am listening now to my recent built 45-76 amp. Used James transformer that I find a very good compromise price quality.
I am using a 01A preamp to get a little gain needed for a 3Vrms input sensitivity amp.
I am enjoying so much this combination. My speakers are Alpair 12P by Mark Audio.

Radu, your amp deserves a topic of its own - maybe start a dedicated thread? Beauty is more than skin deep - do you have any shots of the internals?
Cheers.

I have the fortune of having dealt with both Radu and Oliver. Both make really great stuff. I think the circuits and build philosophies are somewhat different and the iron used is always different. That said, the results of both are undeniably awesome. Radu has a blog with his stuff on it. https://simplepleasuretubeamps.wordpress.com/

Hi rabbit,
Quick question... just to take it off topic in a different direction... :D Do you get enough volume from the Type 45 SET into the Birch Ravens? I'm thinking of doing something similar (well, similar efficiency, no crossover) and your opinion would be helpful.
Cheers.
-
Before the Raven's , I had owned a couple high eff speakers from Omega. 2 watts is more than enough. I feel the output transformers are critical and worth the extra $$$$ . Recently installed a Mullard GZ32 from 1966.. great rectifier :thumb:

Thanks Dwight - I may just give it a crack once I get my next amps built. I hope you are right re the transformers... I have 2x ~5.5kg of custom nano-c core awaiting my build - plenty of inductance and wide bandwidth. Power supply probably matters too.

Is that a 5" Lowther with a phase plug?

Dwight
-
It looks like a Lowther DX55 with a different phase plug, but I can't be sure without seeing under the hood. If the speaker is rated 92dB, I would imagine the Lowther is crossed over at 6dB/octave to knock down some of its midband peak.
-
Love the 45 tube.
I finally got a chance last week to get a pair of the EML solid plates, in place of my vintage 45 output tubes.
Wow, what a difference, in my Korneff.

Hard to tell, but I doubt it is a Lowther. Tang Band W5-2143 looks to have a more likely surround, phase plug, whizzerless... and cost. Could feasibly be used in "92db"sensitive speakers. Apparently really nice sounding drivers, especially for the price.
Cheers.

You're 100% correct. Looking at the response curve it gives an honest 93dB above 300hz or so. I could see this used successfully in a two-way with a first order crossover at 300hz or so. You would get a the entire midrange and upper frequencies out of a single driver. The lens/phase plug could be used to tame some nasties up around the 10khz range.
I think Tangband is underrated and is a good choice some interesting DIY designs. I like that they have a good range of high efficiency, wide band drivers.
-
Interesting, I look forward your sound impressions.
I've only had 3 listening sessions so far, but the EML Solid Plates are better, in just about every way, than the vintage 45s I was using. Bass is more solid, midrange clearer, highs more extended. Overall presentation is more stable. Vocals are more lifelike, I'm hearing more details than before. These were not cheap, but I think they are well worth the money.

Looks like you are using the TCs to bypass larger PS capacitors. Curious to know what you think - what are you bypassing and what changes have you noticed?
I have some a set of TCs sitting on the shelf for my whole PS and have been considering whether I should replace and/or bypass them in various potions. I'm jumping the gun even thinking about it - best to wait until my amp is built and settled in before making a decision.
Cheers.
-
I use TCs in my 01A pre. I used them straight, no bypass. I find bypass caps to not be worth the money. I am taking a break from audio building. Working on an old laboratory tube "tester" from the 50s.
-
Docere ,
The TC caps are bypassing the 45's. the sound field appears to have expanded & move forward a bit. :thumb:
It appears the C-R-C filter is for the drivers. I am no expert on the Korneff circuit.
I should have the EML DHT PREAMP next month.. fingers crossed :roll:
Dwight

Hi Dwight,
Thanks for the info about the sonics! To share right back at you:
The 10uF TCs are bypassing the output stage electrolytic power supply capacitor. That electrolytic capacitor has two separate sections (like two capacitors in one); it has a +ve terminal for each section (2) and a common -ve terminal. Each +ve terminal appears to be connected to the output transformer via a red wire. You can see each TC connected from a +ve terminal of that same electrolytic to ground - the TCs are bypassing the output stage PS capacitors.
The adjacent electrolytic capacitor - connected via the Kiwame (light green) resistor to the output stage electrolytic capacitor - is the driver stage power supply capacitor. You can see the red wires running from the +ve terminals to the driver stage.
The 45 cathodes are bypassed by the 40uF Clarity PX capacitors. You can see them connected to each end of the brown (Mexico manufacture) Mills 12W cathode resistor.
Hope this helps.
Thanks sfox also - good to know about the TCs... I'll run with them for a while.
Cheers,
Ray

I've always wanted to try a 45 amp. I've got a good pair of efficient Omega speakers. Are there any amps that are at or below $1K that are worth trying? I can't seem to find any.

Oliver's Korneff is where I would go. I think that is sub $1k.
Hope I get to hear that EML beast before it leaves. I have to tell you, I am done with resistor volume controls. TVC all the way. OK, I will ignore that resistors are all over the place in the rest of the circuit. Oops.

Olver's version of the Korneff will only be less than $1k if you choose vintage RTR Tamura transformers. The cost of new, high quality iron will push the price to $1,200-1,500.

I have to say that I am not a huge 71A fan. But that's me. I really prefer the 01A. Comparing it to a relay driven R2R attenuator, a Khozmo attenuator and a TVC, the TVC won out for me. But as you say, YMMV.

Hi Dwight,
Looks interesting - is that the EML20B Oliver was looking into building for you? Is that the PS on the left... or a different amp? What will your system gain be?
And finally, how are those dc10audio working out for? I'm thinking of moving to smaller speakers and keep changing my mind - I really need to write down what is important so I can maintain perspective...
Anyway, it can wait until the new monos are built. Today I completed the drawings/specs for the Delrin sub-chassis and panels... but still have the stainless chassis design and hardware BOM complete.
Your system is coming along nicely - well done.
Cheers,
Ray

I find the TVC more detailed than the khozomo. The one I used was his standard with upgraded resistors.

I've 2- 45 amps both TSE's. One with EP the other with Edcor Iron. Work great with OB.

Docere,
It's the EML 20b DHT PRE by Mr Oliver . Power supply on the left. The 20b's mu is ~ 21. The voltage gain is a bit on the high side but perfect for driving my setup. :wink:
The dc10 audio speakers are outstanding but the 45 SET limits the speakers to a smaller room. Please post build pics once you start your project !
And thank you for your kind comments :thumb:
