Hey gang, I was looking to see if anyone could help troubleshoot this one for me, as I'm pulling my hair out trying to figure out where i've gone wrong.
So typical issue, it passes sound until engaged, then nothing. LED is wired the right way, and solder joints are decent. My biggest question is whether or not i'm even debugging this properly. I've hooked it up to a known good EHX 9v adapter and have my multimeter set to the 9v setting. With that I'm getting voltage to a good portion of the components. All IC's, diodes, and J201s are getting voltage.
I've Attached a screenshot of the circuit with this legend. Red means it's getting what I believe to be an acceptable amount of voltage (it's ranging from 4-15v on the multimeter), yellow is a voltage that looks suspect, and no marking means it's not getting any reading on the MM. (I did replace R1 with a tested 1M resistor, no change).
I did substitute some resistors, of which were:
2k2 for 2k7 (R17)
2k2 for 3k3 (R6, R10)
100k for 120k (R18)
10k for 12k (R21, R22)
I didn't figure these would have made that much of a difference, but without the schematic, I could be horribly wrong
Thanks in advance!!
