Yes, I'm having trouble getting a meanwell 1w 5v converter. Had to
order another mfg with the same footprint.

Nice part, but I need isolation. And I don't need much regulation.
I need a simple half-bridge or full-bridge oscillator/driver chip. One
of the Ixys gate drivers might work.

No, forget the amplidynes and just mechanically couple the engine to a
rotary woofer:
https://en.wikipedia.org/wiki/Rotary_woofer
Even better, fit a fast servo to modulate the pitch of the bypass fan
blades on a turbofan jet engine.
"Regular concert goers judged that the best sound balance was usually to
be heard from within large concrete bunkers some thirty-seven miles away
from the stage, whilst the musicians themselves played their instruments
by remote control from within a heavily insulated spaceship which stayed
in orbit around the planet - or, more frequently, around a completely
different planet. "
How about a big tank of very high pressure air, like 5000 PSI maybe,
and a fast servo valve? That would be loud.
If the gas were an oxygen-propane mixture, and you ignite it, thermal expansion would add pressure gain.
That sounds like an audiophool product.

from the stage, whilst the musicians themselves played their instruments >>> by remote control from within a heavily insulated spaceship which stayed >>> in orbit around the planet - or, more frequently, around a completely
different planet. "
How about a big tank of very high pressure air, like 5000 PSI maybe,
and a fast servo valve? That would be loud.
It's been done. Look up Auxetophone and Stentorphone. Horace Short.
and Charles A. Parsons (of turbine fame) were among several inventors of these compressed air amplifiers. Auguste Stroh is anothr interestin
audio engineer.
