There is in this case because the amplifier's 120VAC blower has no 120VAC
tap.  Thus, a neutral is still required.  See follow-up posting.

I should be OK from this persepctive and I also calculated 30-amps.  I'm
assuming that the tw-phase breaker should never be rated at more than the
conductor's safe current rating.

And there's the fly in the ointment!  The blower is the only 120VAC
requirement, thereby requiring a neutral.
