Usually if they are shorted it doesn't matter if they are disconnected or not. Are they both the same or is one of them a IRF530? There may be some collateral damage upstream so make sure you check for more bad parts.

The big capacitors are in the way of the other one so I can't read it. I tested the other from the underside of the board and it has continuity between 2 and 3 also. Is it possible to do this job without a special type of soldering iron?

The only real danger in dealing with any type of FET is static electricity, it doesn't take much destroy then when they are NOT in the circuit.

I just ordered the mosfets. If there is something else wrong with this amp, could it ruin the new mosfets right away?

It may not matter to you at this point but there are several cheap sources of IRF530/9530 and similar audio-compatible mosfets, who supply parts with an "N" suffix, as in IRF530N, 9530N. These types are modified for switching applications and despite assurances, they aren't as good for audio as the original type. Chinese suppliers usually ignore the difference and even their own advertising by sending you the switching type regardless. Watch that any local source isn't just reselling the N type too.

Thanks. I started a thread in the 'parts' forum before buying them today. These are what I ended up ordering:

IRF9530 Vishay / Siliconix | Mouser
