1 Disconnect the speakers
2 Connect the multi-meter (MM) to channel 'A'.
3 Feed the amplfier a sine-wave (1000 Hz) through a pre-amp or pink-noise.
4 Set the MM on the AC Voltage setting. 1 - 150 volts range.
5 Turn up volume and take note of voltage on channel 'A'
Note - leave volume on this mark (ie. voltage will read 3.25 volts & use this to compare the other channels)
6 Mute amp or turn off and connect MM to next channel - 'B'
7 Repeat step 3 - 5 for ch 'B'
8 Advance through all channels and take voltage-level notes.
Make shure that you leave the volume control on the same setting when testing to get a correct reading. Always use the MM on the "V AC" setting. I would recommend using a shunt-resistor (8 ohm, 200 watts) in parallel with the MM.
You can also use a oscilloscope to check the channels... but alas, much more difficult.
Best of luck,

NB - Why don't you take the amp to a qualified technitian to get it checked. Accidents happen all to quickly!
