It worked! Thanks again. I used a 10nF. One non-issue is that if I turn the speed knob counter clockwise (faster speed) LED gets stuck to ON until I tweak the both the wave and speed clockwise.
Got rid of C15 and it seemed to reduce the magnitude of the tick, but it is still there. I am still using a LM358 for the op amps. Will send an update when I replace with a TL022.
Thanks for the advice!
Thanks for the reply. Didn’t have TL022s in my stash, but will put in an order for some. Will let you know if that works. I have seen some of your responses on related/other posts. Thanks for your contributions!
Pitch Witch is ticking and looking for any solutions. Ticks in conjunction with speed knob which sets the rate of the LFO LED.
I have verified component values and soldering to be good. I have tried switching the RC4558 LFO IC with a TL072 and a LM358 as recommended with this issue.
