What if they amp is only turned on when it is being used and the cab on the other end is connected to that head through the selector. in essence the load is always on it right?
I dont leave me heads on when i am not using them. The one being used will always be connected to a cab when it is on.
all others will be off.
The system selector was designed to allow quickly changing amps and speakers for comparisons..... in those cases you need to have the amp on.
If you just want to be able to connect several amps and several speakers in any combination wanted, and NOT have the quick comparison feature, then you are as well off to put a number of connectors on a panel and simply use a "patch cord" to connect any combination wanted at the moment.
That may be what you have now, I'm not clear from the description.
It is much easier to obtain, easier to repair, and unlikely to have any problems in the first place. It is immediately obvious what connection is made, and far less likely to lead to mistakes. If nicely done, it can be somewhere between "retro" and slick.
Your choice what connectors you use..... almost any will make a better contact than the selector switches.
If you only turn on the amp when a speaker is connected, that's the same as "normal" use of the amp, and obviously won't be an issue.
