Issue with turning off JCM 2000 TSL 100

The power supply that is involved in switching the relays (and make the leds flicker), is the 24vdc rail. That's the one you need to look at, not the +/- 15vdc.

BUT... Because this is happening on power down, the relays are just going back to their normal state. I would not worry about it too much. The caps are just draining out and the relays switch out to their normal state.

Leave all the channel select buttons out and plug no footswitch in. What does the amp do?

Hey,

I've haven't been able to spend much time with this in the past few weeks but I do think you are right on the money. With nothing plugged in and none of the channel buttons pressed in, there is absolutley no issue.

Would fixing the power supply be somewhat doable if I could set aside a weekend to spend with it?

I'm glad it's not a huge issue, but would love to get it back to normal.
