Greetings Salas, just a note to let you know my pre-amp is still singing. My fiancé likes it more than me I think 😀
Stajo is either sailing on his wooden 6V6 or he listens to drones and tones watching on his Soviet scope. His silence is rather suspicious.😀
Stajo is sailing in his warm bunk, watching an 8-year old soon to wake up and in a while go to school🙂
Cool video, no I havent yet tried the USSR. Cathode rays are cool.
Actually I plugged the barge in a little quickie yesterday. Without AC filaments referenced to anything. That makes a wonderful sound😀
Then I tried to silence them with referencing them first to ground then to to different potentials with a pot divider from B+
I made it so I can go from +5 to +95 volts over gnd, but it made small differences over ground ref wich still make a little hum. I guess that signal taken from a cathode that is only an oxide layer from a 50 Hx filament is hard to accomplish. I will go to DC (District of Columbia) today.
I also remade the schema a bit, will post later.
Full to the gunwales or I'll walk the plank

Maybe the chokes cases need a ground lug too? If the plate they rest on is grounded already then again not. CRT "oscillographs" are real time update and sometimes "laser sharp" even when vintage Soviet. 🙂
Yes, it was an early shot but today is "work-from-home" day so maybe I'll come with some updates whilst you get your beauty sleep😉
Me sleeping beauty, when you pricked your finger on the 6V6 spindle the other day...Watch it, good fairy gives 100yrs sleep for such if she happens to be around.😀 Tchaikovsky - Sleeping Beauty Waltz - YouTube
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.

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:
