What are those things?



Gareth.

Interesting.

most of the failed power modules i have opened up show clear arcing on
the power device slugs. They look relatively clear on yours.

It does look like a couple of the SMT transistors are damaged.
Its kind of hard to tell from the picture if that's true or it was
damage from prying the case off.

The epoxied power device slug leads do look a little close together
on a couple of the output devices.
