how to bench test an amp
Depends on how deply you want to test. If you just want to check for power
up and basic circuit continuity than a 12V battery and DVM is all you need. I tried my battery charger as a bench P/S and it didn't work. I needed to connect a 12V battery to the circuit in order for it to work ((??)). I use a pair of small-ish gell cell batteries and a wall-wart trickle charger. The 2 cells wired in parallel give 14 amps at 13 volts. I have an old sony mobile ES casette deck, pair of 4 ohm PA speakers, and a profile amp. I can patch these components together quickly depending on what equipment I am testing. Wish I had an o-scope....

how to bench test an amp
YOu can go as simple as Garrett said or as elaborate (or more) as me. 200A
power supply 0-20VDC, multiple signal sources (PC, DVD, CD, FM, Arbitrary Function Generator, etc...), audio distortion analysis, and on and on. Hpwever, at the bare minimum you need a 12VDC source capable of delivering about 5A to power up most amps. You'll also need a source to patch into it.
