Well, on the other hand...
I was packaging the power amp to work after removing the Marshall preamp completely, and...
although the big power FETs are all good, and run cool, all four of the OTHER active transistors in the amp run so hot you can't touch them - little TO-92 plastic things with no heatsinks. So I got a schematic, checked the amp against it, found they had indeed used those parts values, and wondered - is it characteristic of the Marshall sound, in whatever form, to run components just barely below destruction?
