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.
