I guess I don't understand that. The data sheet shows the assignment of each pin, which for the 992 is ECB looking at the flat side. The circuit board in the amp has the diagram indicating what each pin is supposed to be: the pin with the arrow is E, pin on opposite side of plate is B, and pin without arrow, but on the same side of the plate as E, is C. This is shown in the diagram Pete posted in post 31. Am I missing something?The replacement transistors should be reversed from the originals when in position. BCE vs ECB.
OK, I can check resistors, and I think I know how to check if a diode is ok, but I do not know how to check a transistor. What do I measure on which leads?Check everything.
The ceramic caps should be good.
So resistors, diodes and transistors get checked.
I'll check the resistors in situ, and only lift one leg if the value is off.
The metal can transistors are always suspect.
