I took the unit apart and cleaned all the button membranes and the contacts on the front panel so we’ll see how that goes. I also checked all the caps on the power supply board with a de-5000. Some of the capacitors were reading double the rated capacitance with the ESR value reading 0.0 (used 120 Hz). Does that mean there are other nearby components that are getting turned on and messing with the reading or that the caps are going bad? Either way, I ordered new low esr Nichicon capacitors and I’m going to recap the whole thing since there are only a few and they are all generic questionable quality caps. Is there any reason not to use low esr caps? I’m a mechanical engineer by trade so I have basic circuit theory knowledge but some of the more advanced concepts I’ve yet to learn.
