Hi Jim,
        Many years ago, I used power amps in an attempt to run tesla coils
(mine could go to 200kHz).  They all blew up!  The coil stores energy and
can dump it back into the amplifier and BANG! - the output sections blow
out).  The impedances are also very messy for an audio amp to accept.
Perhaps a more modern amplifer would protect itself and if more care were
taken it would work.  Be very careful.....
