When you get the power switch fixed, the KA 7100 amp is a good candidate for a switchable power switch.
I have a switchable power switch for all my systems and plug in all CD, TT, RTR etc into it also. That saves all the switches from wear and tear and I can unplug all of them by just unplugging the switchable power switch. Why unplug them, well for the ultimate in lightning and power surge protection.
I find switchable power strips cheap ,at estate and garage sales, usually a dollar or two.
