Total noob to the site, well experienced in repair. Can't find any threads on the subject. I have a red knob Power Chorus, the chorus doesn't work. Replaced U18, 19, 11, 12. Oscillator works and switches as it should. Would help if I knew how this circuit works, what to adjust the pot to. Anyone out there worked on this circuit?

Thanks, Dick.

Hi dbillups,

Do you have a link to a copy of the schematic?

Y'all are gonna love this. When I ordered parts, I ordered 2 of everything, I always do that with inexpensive parts. When I replaced the 2 chorus chips I accidentally swapped the two, installing them in the wrong holes. I spotted that after several returns to troubleshooting. I removed the 2 that I placed wrong, put the other 2 in the right places and VIOLA! All fixed. Thanks to all who considered helping, it was operator error!

Dick.
