I don't remember the max permissible grid leak for 6V6 tube but 100k pot//100k leak gives you a 50k pot now. It would be faster rise time if the sources permit 20k pot.

Yea okok. I know you guys enjoy some pix while Im putting on the second pot of coffee. The barge is playing now, all uneathed and unisolated so its still picking up some hum/noice. And its extremely microphonic. It could be a challange to get that away. Plonging a tube with finger almost makes a loop.

I first run it on a Hafler EL84 and subjectively I like that better with its own volume pot and no pre. But now in a 6L6 Candela and its rocking. Firm (ish) bass (feel it in the walls) and decent mid/top. Well its still early.

Brb after coffee.

Since its so darn sensitive I might have to give it an overlook on EMI-shielding, earthground the metal and try to isolate physical trafo-hum etc to give measures a fair chance. I might put in a 20k plastic Alps also but thats gonna take some time. Poll?

I use a Squeezebox for testing, 100-200 ohm out 2 V so it takes a 20 k no probs

Salas,
If you had to split the output of the 6v6, would you use line output after cap or phase splitter before the cap.

Talking Soviet equipment, I found this signal generator localy which at the price is juggling with nice THD numbers:

Генератор сигналов низкочастотный Г3-118

Hope you guys are able to catch cyrillic and tell me what you think.

It's near the price of this one:

Instek SFG–1013
