Good day,
While working on a troublesome plugin, I had cause to open up my TM504 to check the power transistors (as one does). I am surprised to find that Q22 and Q30 (an NPN from one middle slot, a PNP from another) have been cleanly relocated from the PCB to a location about 6" away, and heat sunk to a chassis member there. Fancy color-striped wire was used, and heat shrink etc: it looks like a pro job. Anybody know what's going on here?
And you're going to ask me if they are the OEM PNs; that will require more disassembly.
