I'm looking for a modern day, widely available, low price replacement for either of the dual guate MOSFETs as shown below.
Looking for thru-hole and not surface mount... unless there is simply no other choice.

These parts are going to be used in is an rf amplifier circuit operating in the HF band up to at least 30 MHz.

The parts list calls for one of the below...
  • 40673
  • 3N211
  • 3sk40

But none of these appear to be widely available now except on eBay and/or surface mount from distributors.

I will be buying a small quantity of these if we can find a reasonable replacement commonly available from distributors.

Thanks for any help.
