If you know what could be wrong and have no clue how to fix it, to be honest something like that is the first warning sign that you shouldnt do it yourself.. Just wait for him to get back.

If you open up the amp you can check the wiring for loose connections and what not, but then that voids the warranty. If you're lucky it'll be the wires going straight to the speaker, the knobs, or the input. If you have an open back amp just check the wires going into the speaker and wiggle them around gently while it's on and listen for crackling. Same deal goes with the knobs, turn each of them individually and listen for pops and cracks in the sound. For the input, just plug in the guitar while its on and move it around gently and listen as stated above. If none of those are the problem then I'd bring it into a shop unless you have someone familiar with wiring to help you.

1. Get tools need to pull amp apart and test (screw drivers, pliers, picks, multimeter can be used to help test connection, flash light, soldering iron and so on)
2. Take the amp apart and pull the board out were you can look at it from both sides. While doing this also keep an eye out for loose wires and so forth.
3. Discharge capicators so you dont kill yourself
4. Look over the circuit board and see if anything catchs your eye as loose.
5. Get out the flash light and over it again.
6. Repeat step five but this time giving each component a wiggle to make sure its secure
7. Still cant find it break out the multimeter and start testing each compnent
8. If you find the component resolder it
9. Put amp back together and your done

Dirty contact, do options 1-3 but this time purchase contact cleaner and clean the pots you might suspect are the issue. If that doesnt work replace.

Isnt usually tubes that cause a fluctuation in volume, I dont know if your amps are tube or not though.
