The ADA4895-2 that Howard chose to drive the IRF510's might turn outtoggle quoted messageShow quoted text
to be a good high volume choice after all.
Can buy that dual op-amp from analog.com for $3.21@1000, presents almost
no load on the preceding stage, and apparently drives the IRF510's without a transformer.
Preceding stage with the HA-5002 is a voltage follower and a 1:13 impedance ratio transformer.
The HA-5002 is spendy for what it does here, should be plenty of other ways to implement that.
