Bias wiggle trem w/ cathode bias 6V6s

Hey Seppo,
I would think you can use PPIMV with bias vary. I haven't tried it though.

Thanks Smokebreak!
I will try. Yet I think which one to build, sluckeys AC15 or Ampeg 12j. I think that the AC15 tremolo is different than the Ampeg. Try to know both fine amplifiers. Also wanna try vvr or some regulator.
Need guiet good sounding amp.

If you only have one triode to use then you can't build the AC15 circuit. It requires 5 triodes (6 if you count the input preamp triode also). It's a totally different circuit from the simple bias wiggle Ampeg circuit.

Thank you. Yes its very different. I have lot of 6sl7, 6sn7 and 6sj7. Gt:s and metal and russian too. I hope that same resistor values are suitable. (12a*7 vs 6s*7 In ac15)

Last i bild Brown Note Foxy18 amp. I used 6sj7 instead of ef86, with jone's octal one values but biased with led. And 6sl7 instead 12ax7, then i chanced resistor same like aikens demonstrated (desingning LTP) on his site.
And pa with 2 x 6ak6 tubes. It was almost too hard to me, but finally it work.

Im not understand lot of tube amp, but I think it will be completed with a small tweak .

SeppoL, I just now realized that it was Smokebreak that asked about bias wiggle trem and he only had one free triode. Sorry for my confusion.

No worries no sorries Sluckey!
btw. Have you experienced, does octal 6SL7/6SN7 work fine with same resistor values as 12AX7/12AU7?
