I'm having trouble getting sound out of my Stella. After lots of testing I can confirm an audio signal coming out of lug 2 on the 10k level potentiometer and going into the TBA820M on pin 3, but no signal comes out of the TBA820M on pin 5. I do have voltage on the positive side of each of the electrolytic caps.
I'm wondering if it's likely I have a bad TBA820M chip, and if there is any more specific testing I can do in the circuit to prove this? Does someone have a list of the positive voltage values for each electrolytic capacitor when the circuit is powered at 9 volts I could use to double check my circuit? Or should I just order in another TBA820M chip and cross my fingers?
