I doubt Peavey, too... Their own flagship of the era, the CS-800, was a monster in it's own right, and I cannot imagine the need to contract out the production.
20, yes, 20 output transistors per channel. Same 2000VA/1800Watt's for the PT.
One hint I missed that may make it easier was this
Who actually made it I don't know, could have been contracted to SAE but that's not what the name says.
From that, I think we can be pretty sure it's not someone
known for building their own amps...
From that, and the fact that the banana jacks and RCA inputs
look original, and it has 1/4" inputs as well, that would indicate a company better known in the home, but with pro ambitions. I think that rules out JBL, EV, and other companies that had a firm hold on the pro market at the time.
No, we're dealing with a home player here, I think... Now to think, it would be a company that would
need a lot of power- Infinity was not building their own amps at the time, so I think it's not one of theirs. Who else was a home company with pro ambitions, whose speakers required a lot of power, and who may have been a client for SAE? The answer lies there.
