It depends on the monitor. The amp could be a completely separate
board that only requires a single low voltage power supply that you
could get from a 'wall wart' adapter. If you're unlucky it could be
part of the main board and almost impossible to run without the rest
of the monitor. If your plan fails, there are small, inexpensive
amplifiers that would do the job.

Discharging the CRT is something you can easily and safely do
yourself. Do a google groups search for instructions. All you will
need is a long screwdriver and a piece of wire. The CRT can hold a
painful, but not dangerous charge.
