It's an input switcher. No noise, works perfectly fine. Power unit is separated inside the box. I will ask the owner of this T2 (Stanislav) to join this thread.

Few pictures of KG DIY T2 top notch assembly by Helium (all pictures by Helium):

One more T2 from St Petersburg from my fellow audio friend Stanislav. What about 86-pound single unit T2?

Couple of weeks as I brought home KG DIY Т2! Big mate with a BIG sound! 62 pounds of the best electrostatic sound ever! Below - T2 with SR-Omega and HE90 (and few of my electrostatic headphones):

So that no one gets confused: Dmitry (Demograf) has nothing to do with the MSB electrostatic amp.  The use of his picture on the MSB web site was a real surprise for Dmitry.

Since MSB is using the image of Dmitry Gubchenko (designer of “Demograf” audio equipment from Russia) it would be nice to compare the design of the MSB electrostatic amp with the ones which Dmitry is making.  Also, Dmitry (as far as I know) prefers HE90 and SR-Omega e-stats, rather than the...

I have no idea re where did you get this figure from, but anyway I’ve paid less.  Besides CD3000 I’ve got HE90 (the Orpheus), 2 pairs of SR-Omega (the original Omegas not the 007), 009, both types or R10 (bass-heavy and bass-light), two types of 007 (including the 70xxx drivers) and some other...

How interesting)) the seller is probably the same (I don't fully remember his name on eBay). It looks like he has one more CD3000 for sale. Both my CD3000 were at home (at least this morning)). The seller was fine, the pair he sold to me is really mint. I haven't decided what to do with the old...

I’ve recently bought a second pair of CD3000.  I like the CD3000 sound, but I have better cans, including Orpheus Set, original Omegas, both R10 (baas-light and bass-heavy), etc.  But this time the CD3000 I’ve bought are brand new (!) old stock.  Ark, headband and ear pads material of CD3000 is...

Looking for an advice re the best amp to drive the Abyss.  Sound signature – warm, not bright, high res, good bass control (bass should not dominate), no harsh, etc.  I do have Omegas, the Orpheus Set, both R10, etc.  Would like to buy Abyss (which I have heard) mostly for rock and metal. ...

  Are you from Moscow?  I have new R10 ear pads but not sure if I want to sell them.  I have two R10s - bass-light and bass-heavy.  Let's keep it touch!  Sent to you a PM.

I’ve got the bass-light version #0457 for almost 2 years now, and recently have also got the bass-heavy #1182.  The bass-light are from 1989 production, the bass-heavy were made in 2004.  Both sound great!  I like the estats’ sound (have got the Orpheus set, the Omegas, etc.) but R10 are really...

CD3000 vs R10 (bass-light) differ a lot.  It was discussed many times on head-fi.  CD3000 are still very good headphones, especially for the money.  They are a bit bright on the mids, the scene is a bit too separated for left and right (these is a small gap in the middle).  The sound signature...

Thanks a lot!  I also think that 1300 is a more realistic figure.  I guess if we find someone with the highest # ____ of R10 – it would give the answer.  I have heard a rumor that the R10 were originally produced by 200-pieces bunches.  But some people say that the R10 within “the same hundred”...

Hi,   Did you find the answer?  I asked the same question couple of weeks ago in R10 thread - no replies.  I have got #457 (bass-light) of 1989 and #1182 (bass-heavy) of 2004. I haven't seen # higher then 1182.  Since the last year of production was 2004 I really doubt there were another 800...

I’ve got #457 (bass-light) for 1.5 years now and just bought bass-heavy #1182 (on their way).  I wonder what is the highest #____  of R10 ever on head-fi (or elsewhere)?  Just curious how many R10 where actually produced – 1200, 1300 or 2000? Also to my best knowledge, all R10 from #1 to #200...

Hmm... Reading the comment above I would rather think twice before sharing anything in such a friendly environment))

Eric, it's not that expensive)) the parts can be seen on the pics, the prices are known, it' not really hard to calculate. The input attenuation transformers (which don't have name on) are Stevens & Billington TX102 mk3-I. The Hashimoto interstate transformers are 107A (are used as phase...

Quote:   The above doesn’t take into account the DIY auto-transformers which almost double the swing (can be seen on previous pics).  The dynamics are also raised by extended power supply.  If there would have been any concerns re voltage swing, we could easily use the tubes with e.g...

Quote:   I don’t like bright sound, but I’m not a basshead either.  So the idea was to make it an old school “rich & warm” sound, but with good details and dynamics.  The bass of the amp is reasonably extended to first of all please HE90 and 009 which imo benefit from solid body (and...

Quote:     Eric, bonjour!  Yes I have heard BHSE, I have also heard and/or owned few other top electrostatic amps.  BTW, there is a large and active headphones’ community in Russia and former USSR.  Here is our forum: http://forum.doctorhead.ru/index.php?act=idx   009 + BHSE are a...

Quote: As far as I recall it’s 260-265v between cathode and anode and with reduced anode current the tube does not exceed its max settings on dispersal power on anode.  In this mode the voltage on the anode can safely be higher than nominal.  Also, as a current amp pentode shows better...

Quote:   The trick is with the current in pentode mode – it should be reduced.

AL4 are used as pentodes.  Dmitry told me that he first had to find the way to cook them right. The rest was piece of cake))

Quote:   Eric, thanks for posting the links.  Piotr Ryka in fact wrote an article re this amp at his site www.hifiphilosophy.com couple of months ago.  At the time the amp still had EL8 pentodes but few weeks ago it has been upgraded to AL4.  PU has been also upgraded to provide higher...
