Thanks so much for this one. It sounds great. On mine, I rearrangedthe diodes so instead of both going to vol #3, one of them uses a wire and a switch to turn the octave off, like I've seen on other Octavia clones.
I used a 42TU011 transformer and D9B diodes. Then I used 2n5087 & 2n4401 transistors. I've read mixed advice on whether you should use high or law gain on this, but what I did sounds good to me.
I don't have a schematic to draw from, but if you follow the jumpers for Q2 collector, it connects directly to V+. 8.5 is roughly what you would get after passing 9v through a polarity protection diode, so it seems to be reading exactly what it should.

Any chance someone has the rough collector voltage values for Q1, Q2, and Q3?
ReplyDeleteI’m getting 8.5V at Q2 collector which seems odd…
