Steve:
Yes, my on-off switch burned up a couple of years ago, but I haven;t
replaced it because I don't feel like pulling the front panel off. I use
the switch on the power supply anyway. Maybe someday, I'll fix it!
I did put a mod in to disable the clicking relay. Since I don't use an
amp, there's no need for it.
