If this is affecting any and all output channels, I'd think it's a power supply problem, e.g. a shorted rectifier diode. Then it would be a fairly cheap fix. Otherwise Technics gear was commonly using proprietary power amp hybrids that may very well be long out of production and not easy to get, and would likely have suffered in such an incident. All bets are off in that case.

One word: Proofreading.

@LemmyAK47 can you take a couple of pictures of the inside of the amp so we can see what this unit is? I attempted finding a service manual but no luck there.
