The PL1100 Equalizer I have didn't fully work. The knobs were so dirty, I could have used pliers to turn them. Some channels didn't work. I took the entire thing apart, recapped the boards, and cleaned the knobs and sliders. Hooked it back up and it sounds excellent. I also replaced the C6 capacitor on one of my OEM PL400's and did the Gepetto diode mod while I was at it. All good in my house!
