Does anybody have the voltage readings for the transistors handy?
I was getting good volume boost but a lot of white noise with the gain turned up, the audioprobe found the noise started at the drain of Q3. So I swapped it out and now I'm barely getting unity gain with everything maxed out.
I'm going to get together a few more 2n5457s (smd-to-adapter board) but was hoping in the meantime to get the transistor readings from a working build.
Thanks!
Here are my voltages:
