So I'm building a rat and I'm gettingnjo sound from it at all.
I probed the audio signal and it's all good where it enters pin 3 on the input, but I get no signal on pin 6
Voltages
1 8.46v
2 0.62
3 1.207
4 0
5 0
6 0.486
7 8.97
8 0.2 but this seems to be moving all over the place (due to the capacitor connecting pins 1 and 8?)
Is my lm308 shot?
I've run a scraper between all the solder joints and I can't find a short. Reflowed all the joints. Checked continuity on the socket pins...
Alright. Try putting another opamp in your builds to make sure (I think TL071 or similar should work with compensation cap removed?). I could'nt find any obvious mistakes on your board either.
