A disclaimer : I don't know the first thing about amplifier design.
The Pass amplifiers use outrageously large heatsinks. I understand this is due to the fact they're class A, and inefficient.
Here's my noob question:
What is attached to the heatsink?
I always thought the mosfets that amplify the signal are attached to the heatsinks, but I've noticed in the Mini-A thread that the mosfets aren't.
Are the devices attached to the heatsinks part of the power supply?
(I know, I know, noob question...)
I even went downstairs and dis-aseembled a broken amplifier that I have, to figure this out.
The bad news: there are six wires that lead to the heatsinks, but I can't figure out what's attached to those wires.
The good news: There were two fuses inside the amp that were blown! Maybe my amp isn't broken after all 🙂 🙂
(It's been sitting on a shelf downstairs for three years now...)

The diodes/rectifiers in the power supply can have a heatsink, but yeah, the mosfets themselves are the ones hooked up to the big heatsinks.
