If the new cart doesn’t miraculously cure it all, then it’s some proper diag I’m going to be into.
When you say isolate do you mean extricate from heatsink or isolate the transistor by desoldering ?
Btw I’m also assuming, that so long as I stay clear of anything around or on the mains side of the transformer etc that if I touch the wrong thing I’m not going to get a horrible shock ? Or at least not a lethal one ?
Plainly I’m not going to be fingering everything whilst live, I’ll be using the meter but, just in case.
