I have 2 valve amp heads and a 1x12 cab fitted with a single 12" 8 ohm speaker. The connection panel on the back of the cab has 2 jack sockets and you can plug into either.
Now I know that you shouldn't turn a valve amp on unless it's connected to a speaker but can I connect both amp heads ( one to each jack socket) to the cab if only one amp is on?
i would only ever use 1 amp at a time, just leaving the other one connected for convenience.
Is this safe?
If so, would the "unused" amp need to be completely off or could it be in standby?
I'd welcome advice from those with much greater knowledge than me!

Do not ever connect two amplifier outputs together, even if one is turned off. There is a good chance of damaging at least one of them.

all in all not good news for either amp
What then, would be the purpose of the 2nd socket on the cab - connecting another cab I guess?
I assume connecting another 8 ohm speaker would then result in a 4 ohm load if it's a parallel socket?
