[Amps] Multiple Amplifier Switching Box

[krishna kanakasapapathi]

I run my TL922 through my Alpha 9500, but of course, the Alpha is in 
standby and is capable of running 1500w through it.
The switch box will be handy, for example, the 3cx1500 takes 3mins to 
warm up, but the TL922 is ready in say 20seconds.
Can he helpful to get on the air with QRO while the other is warming up. 
Plus it can help cycle through all the standby amps
from time to time without having to mess with cabling.
