The transistor that heats up immediately is
bad (excessive C-E leakage).

The DVM test procedure is to use the diode
check function. Imagine a transistor as
two diodes back-to-back with the base being
the common element. Test from base to emitter,
and from base to collector. You should only
get a reading in one direction on each test
(when the base is above either of the other
elements), and it should be around 600 mV.

I check this trans out of the amp with a dvm for short and what is the
procedure? Thanks, Bill
