[TenTec] Corsair II QSK

[Bwana Bob]

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.
