I'm having trouble with my Honeydripper Rev 1.1.2, non-2015 version, using CA3080's. I'm getting filtered sounds, but the envelop is not sweeping the filter.
I've reflowed and scraped solder flux and checked for bridges. I have a USB scope and can follow a signal through IC1 and IC5. The signal at pin 8 of IC1 is a tall squarish wave, after that it looks like a sine wave signal of similar amplitude as the input signal being inverted out of phase. Not sure what I'm looking for. I can see nothing on pin 5 of the CA3080's.
Maybe my substitutions are to blame? I used a TC1044SPCA for the charge pump and connected pins 1 and 8. I used TL074's in place of the LM324. R21 is 2k and C2 is 1n
Pictures and voltages below, any help is appreciated, or anything specific I can look for on the scope
