The increase in value won't cause the amp to produce less power. There is a thread where it shows the resistors under the board and against the heatsink.

Okay, I finally got my multimeter back, and now I can resume work. REC201 and REC202 have 2 different kinds of transistors. Are they supposed to be the same?

Those aren't transistors. They're rectifiers. One is the positive rectifier. The other is the negative rectifier.

I see. If I'm testing these correctly, they seem to be okay. It only shorts 1 way, and that way is opposite between each side of the center pin. There is no apparent damage. Should I order parts anyway?

Rectifiers (in the board) generally read shorted between legs 1 and 3. They should not read as shorted any other way.

These rectifiers read a short between 1 and 3, then they short when and only when neg=1 pos=2 and pos=2 neg=3.

Shorted is 0 ohms. Are you saying that the meter reads 0 ohms 1 way and not the other (lead placement)?

If so, your meter is likely giving you false readings.

The meter is in diode mode, which, if i'm not mistaken, means it acts as a continuity tester. The multimeter could be giving false readings, it is a joke. I'm ordering an new one.

You may not need to buy a new one. If you do buy a new one, buy a Fluke (preferably a model 10, 11 or 12).

If you pull the rectifiers, they should read as OK.

'Continuity' can mean a lot of different things.

Haha, I see. Alright, I'll leave them in.
