selector for 2 amps & 1 set speakers

[apurcell22]

I have 2 systems in the living room and only room for one set of speakers. I need a selector, either DIY or purchased. Any sugestions?
TIA,
Al

Assuming both your systems are SS, then a DIY 4-pole double throw will work and if you use a rotary switch be sure it's break-before-make. J

Actually,
One is SS HT unit and the other is tube.
