Hell, yes!

I've been searching for suitable MOSFEs for a couple of days now but=20
with limited success.  That's why I decided to do the boosted voltage=20
for gate drive.

I had also assumed that N-channel MOSFETs had better characteristics=20
than P-channel, even though I'd MUCH rather use a P-channel.

Many thanks for this little tidbit of information - I think that it=20
just solved my problem!
