i am so freakin stumped
« on: September 30, 2008, 12:48:56 pm »
hi again. i have a ? about output transistors.
if you have a beta lead it has two(?) output transistors if im not mistaken
do both of them have a heat sink? i say this cuz mine only has one heat sink.
my amp also has;
half volume of what it should be
original 3500uf power caps
the preamp has been recapped looks fine
 the 3500uf's probably need to go i imagine
i think i have a output transistor issue
because if indeed there are two of these they most likely handle
the output of sound close to the end of the power amp
do they each handle about 50% of output if this is the case?
i cant read the part #s on either one of them due to them being worn down to the metal from the heatsinks
is a blown output transistor the reason for my volume issue?
-K
