Must sound as good as it looks. Very nice.

Curious, what is sitting on the cabinet in the second picture in the background?

Very nice work...What model are those Silk output transformers? Wondering how it sounded. What's your opinion?

Hello overtheairbroadcast,
The seat is exclusively reserved for my wife.
She likes to study the impression on the dedicated followers of audio faces suffering from audifile nervosa during the audition.

Hello vt4c,
As Hoi predicted:
Bass is rather lean but enought for me.
Middle tone very good.
Cristal clear high tones.
Specs: Pout max=17W,
Bandwidth: -3dB 25Hz, -3dB 32kHz, -6dB 50kHz (at 4Ohm load Pout=12W)
No global NFB.
OPT transformer SILK 5k, plate choke 50H 30mA.
Yes some parts from vt4C too,
Greetings,
Jarek

Sure thats just an amp jareksy13 and not some sort of x-ray gun straight out of a on-line shooter game?
Looks awesome, really nice!

Wow, mthoi, that's quite a mix of tube envelope shapes!

my old ugly clunker from either 1993 or 94 417a/5842q -cheap interstage transformer, 2A3 outputs and One Electron transformers.

I see you're single.

Jeff,
The tubes from left - Sylvania vt244/5u4g, Telefunken Az1 rectifiers, RCA OD3 voltage regulator, Siemens C3g and (behind) Siemens F2a.
I have decided to have a separate B+ (5u4g - CLC) from the B++ (Az1 - CLC) for the C3g.
