Did more testing yesterday but only on one channel as the other is overheating after about 20 minutes, so there's a problem there, bummer.
The good channel still kept dropping in output power, lost about 50w. The regulators after 3 hours were cold to the touch.
The right channel is a puzzler, but I have the left to compare it to, so I'll take some voltage measurements today. Somewhere a transistor is turning on too hard probably, this is where I usually start getting stuck after eliminating obvious culprits and I'll be honest my enthusiasm starts waning, I've been at this amp for weeks. Still, onwards and upwards.
