Hello?John Woodgate.
I do not mind creating with you the scheme you need. This topic is in my interest. It is bad to have unspent potential. I have already helped other people create amps. Therefore, write to me personally.

Is anyone willing to help me by private email
with the design of an amplifier (not Class D) to drive a 300 mA
sine wave into a 170 ?H load (5 ohms resistance) from 40 Hz up
to 150 kHz?? It needs to be a current-drive amplifier, of
course, to keep the current constant over that frequency range.
I have experience with current-drive amplifiers, but not up to
150 kHz and over 40 V output. I guess this is a project for
power FETs rather than BJTs, but that's only a guess. Input
signal can be 1 V into 10 kohms.
This is an unfunded private project, but there
is a remote possibility of payback.
