I've got two amplifiers and I'd like to switch between them. At the
moment I'm plugging/unplugging at the speakers. For reasons of cable
management, convenience and neatness I'd like to use a switch. QED did
one a while ago but it's discontinued, and replaced with a wall switch
which is too 'embedded' for my liking, and pricey.

I was having a look in Wickes for a suitable switch, and it looks as
though a four gang light switch would do it (8 wires in, four wires
out), but this has four switches.

Ideally I'd like one switch - amplifier A, or amplifier B.

Any ideas?

Thanks, Rob

I used a couple of 12v DPDT relays powered by an old psu from a cordless
phone.
One amp has a switched mains-out socket on the back; the psu connected
into that.
That then was the master amp so when it was on, the speakers were switched
to it, and when it was off, the speakers were switched to the other amp.

If neither amp has a switched mains outlet, you could use an 'intelligent'
mains extension block with one amp connected to the master socket.
