Hello All!
Built a Muroidea that I'm not getting very volume/gain out of.
I'm using an OP07 Op Amp instead of the LM308 called for.
I've probed some areas with an audio probe and had the following observations (Volume and Gain pots maxed):
1) No signal coming out of pin 6 of the op amp into C7
2) Signal can be heard from Op Amp Pins 1, 2, 3, 8.
3) Strong signal can be heard going into center pin of 2N5458 JFET (sounds like input signal). If looking at flat side, no change when probed on left pin. Right Pin cuts buzz, but no signal heard.
Let me know where you think I should start looking, or any additional info I can provide! THANK YOU!!!!
