Trung helped me debug my second buffer and it is up and running!  He and Gary are Da Man!   :thumb:

Next is trying a Sure Electronics Class D 100wpc stereo module from PE with the buffer and hear what it is for $44 + $50 for the PS.  If that works it is time for the battery power supply for the amp!

I'm soon to be in the club Trung  :D

BTW, for all of you out there that don't know it, Trung is one hell of a top notch Guy!   If you are on the fence about the Buffer as I was and nervous and un-educated about the entire battery set-up, he will hook you up, answer all your questions, and clearly goes above and beyond.   Thanks Trung for the awesome help :thumb:
True story.  A gentleman and he has been Gary's right hand man for a long time.  Not to mention the fact that he is one of the funniest people (humor, not odd  :lol: ) you will ever meet.

Why else would we name one of our products after him?

 :D

I second that x10!   Trung saved my bacon after my father and I managed to "almost"  build a working model.    :green:

I've been impressed by a couple of the DIY battery enclosures I've seen on this thread. Lacking real woodworking skills, I decided to convert an old storage box into something that would hide my batteries and charger. The inside of the box needs a little wire management, but that will have to wait for another day.  :)

PS. Trung rules. He is extremely generous with his time and friendship. He is certainly a plus for this thread.

Got one more HOOKED on 6H30DR  :thumb:
Wish more come to The 6H30DR club  :wink:

Trung,

For those of us who own a Virtue Audio Sensation integrated amp with the fabulous Dodd tube buffer already built-in ...

What is needed for us to join the 6H30DR club ?  :green:

I sent something to Gary some time ago about this, but obviously the timing couldn't have been worse ...  :cry:

From what I understanding:
(I'm sure more to it, but just few thing on the top of my head)  :scratch:
- Not much room inside the Sensation for bigger tube (taller)
- 6H30 tube draw almost 1A, so it does require a bigger voltage regulator.
- 6H30 tube and voltage regulator will generate more heat.
- More chance the Sensation pick up more RF
- difference circuit for 6V and (or) 12V

Trung-

I finally got the 6H30 worked out...liking what I'm hearing! Went to Gary's this morning to see if the tube was lighting up the way it was supposed to..."I thought it was bright"

 :scratch:

Hi Ted-

Box made it here...now I have a box for another project.

 :D

Any suggestions out there for a cheap DAC? I know Trung, you keep telling me Squeezebox Duet. I don't know if I want to go that route since I'm a Foobar guy!

Foobar sounds very good when used with the AQvox ASIO driver.  I didn't like paying $120.00 for it, but it was worth it on a PC based machine.  http://www.aqvox.com/Asio-USB-Audio-installation-e.htm

We've been listening to DACs over here in Albuquerque and the best inexpensive DACs that we have found are the HRT ( http://www.highresolutiontechnologies.com/products/ ) Music Streamer II+ ($349.00)and the Pro ($499.00).  The II+ is out of stock at distributors right now.  It is being upgraded and repackaged.

I had great hopes for the Arcam rDAC but it just doesn't cut it  :(

YMMV

I've been very happy with my Pop Pulse 1796. It's 24/196 capable and available online for $269.

I was considering putting black knobs on my buffer and was considering restaining the faceplate to get a closer match to my black amplifier. Anyone know where to get black knobs that are a drop in replacement? Thank you,
David

I finally got my buffer up and running, parts been on the shelf for a couple of months while I deal with life.
I find the buffer a real eye/ear opener.  How can such a simple device sound so good.  But I have also been listening to the WarpSpeed LDR attenuator.  Which has presented me with the purist sound I have ever heard in my system. So the obvious question is to combine them both.  Has any one done this?
I am using two 7ah SLA's in parallel with 15000uf cap for power
