So here's the situation. I was given an older Laney amp head, an AOR 50, and was told that it was broken. The guy thought it was just a "pot," which I assumes means potentiometer, or one of the knobs. I don't have a cab, but I want to fix this amp so I can use it or sell it. What is a good way to tell it it is indeed one of the pots that needs to be replaced?

You shouldn't turn it on if you don't have a cab to hook it up to.

buy a cab. turn it on. go from there

you really shouldn't be turning it on without a cab, and you wont be able to play it without one anyways. thats really going to be the only way to hear whats gone wrong
