I got a broken Mac Plus I repaired. Just connecting the power chord (without even turning it on) used to make the main electricity switch trip. I recapped the analog board, replaced the optocoupler, recapped the logic board, and added a diode in the empty location on the logic board to provide SCSI terminal power. Now it works well, however, the screen shows faint horizontal "waves", especially when the luminosity is set low, that disappear only when the Mac is warmed up (very warmed up... they take about 20 minutes to disappear, and the Mac Plus can reach pretty high temperatures). I tried to capture the effect on video but it's not easy. Could it be a power issue? Should I be worried?
Thanks,
