Choice of drivers - DHT or Pentode?

Thanks Paul, I hadn't considered the inductance in the AC path.

Look at it another way, it's made your decision for you.

You can use a single high transconductance triode or triode connected high transconductance pentode, or two stages low/medium mu, something like Will described.
