Quote from: Spenzerleehorton on July 01, 2025, 11:06:03 AMfound the problem!!!!!!!!!!!!!!!!!!!!!!!!!!!!
looked at the  regen pot wiring and there was a cold solder joint on the signal going in, and the wires were swapped round, which only meant the pot was working the wrong way but chnaged that and now its all working and sounds pretty good!!
i'll now mess around with a selection of caps for c23 and see which ones seems best, at the moment 30pf in there.
Fantastic news!

Yes I have gone through the setup process several times, R9 is 2 x 15k soldered together.
IC6 pins 1-3 voltages?

What's going on at R9? It's hard to tell if those two are soldered or one of them is broken.  Also, have you gone through the calibration process yet?

tested voltages this morning and all voltages ok apart from IC6 pins 1-3?
Regen pot still doesnt work?

attached is all voltages and values of resistors tested in circuit.
all cap values and are correct apart from the one shown.

IC6 seems to be the only voltages that dont seem good on pins 1-3?

Yes replacement chip has arrived and testing today, will report back.

i have gone through and tested all resistors and put values they test at in circuit on the other attachment.

The pinout in the 5532 is the same, but they're not the same thing. That's your LFO section which would make sense why the regen pot is t doing anything. Have you gotten the replacement chip yet?
