Progress of sorts... noticed the grounds of the modules weren't grounded to the chassis/earth, did that , one channel now clean, the other better, but not 100%. Found two 33u caps with less than perfect ESR, so changed the lot, better but still a bit of hum present. Will do some more digging today.
Dug out my ETI's, one issue had a lot better picture and I would say they're OMP modules, nice one David.
I actually had a proper look at the amp and it says it's a "C/M amps DL500 PA amp). They really were monkeys back in the day for bigging up their amps, or maybe they mean 500mV sensitivity? : )
