[QUOTE="chipwelder, post: 73431, member: 54"] OK a question the MJE15034/5 transistors have pin two as well as the case as a collector... I am guessing I should use insulating washers on them? as a further point should I insulate the MJL4302/4281's as well, usually just use servisol, but forgot that the metal backed transistors are prolly in contact with the heatsink, so that should be insulated with a washer... or should I just insulate the heatsinks from the chassis? Attached are a pic of the designers heatsink - it is with the Toshiba's Quite a pain the MJE's have different CBE pins to the 2SA and 2SC's the design uses... now I can't just copy his wiring... oh well we learn some...
