if you look at the lettering on the transistor you can see it is not the same lettering size or style
as in repairing the amp yourself i wouldnt recommend it
more than likely there is more damage than what is visable
not replacing all the blown part can cause all your new parts and possibly some of your own parts to blow all over again

sink is prolly angled.
I dont think its worth fixing. Fixing yourself YES, But you got some learing to do.
If the PS is cooked because say someone hooked up the amp backwards then the PS is the culprit.
If the PS went cause the outputs were over driven, U need to fix the output as well.
Take an ohm meter and test the legs on all the big transisters.
One at a time, test every possible leg combo. your looking for dead shorts.
0 ohms!
the meter will do funky things depending on what type of device your testing.. all you are really looking for IS 0 ohms.
When u find those. remove the transistor and test the one again to its side cause they are hooked up in pairs or 4s , again depending.
Check it out! its not difficult.

save the picture and madnify it
it plain as day if you know what your looking at
if you knew anything you were talking about it would show and i would say any advice your giving is useless
there can be any amount of transistors on a power supply from one and up
and theres more to recommending on how to check a transistor that for a short
there are more than one type of transistor and the meter readings are different for each

Didnt look at the second pic.
strange.
Thats how i fixed my first amp. lol
Seemed to work ok and is still working.
Without confusing the poor guy about different types of transistors
I was trying to offer my advice on the most common failure. dead shorts
Remove bad parts and replace with good ones.
Or hell , just replace them all
u cant have just one transistor in a ps.
Let the pissing contest start.

thing is that if he dos't replace all the failed parts chances are he will blow up all the parts he just replaced
amp repair is hot a diy thing
and yes you can have one output transistor in a ps
if you understand how they work
