Yes way back when I had sight I built a heathkit short wave radio and it
used dual gate mosfets.
Good fun lining it up.

Perhaps a caveat is needed here, and that is, if you have
old as-new stocks of wire-ended components, (with the possible

Also, if you're moving in the direction of SMD, then
the easily-installed 1206 former larger sizes are
something to get hold of while you can.

My regret is that a couple of years ago in a clear-out,
I binned all my "geranium" semiconductors and RTL logic chips.

(Not sure, however, if that applies to the 12AT7 up in
the box in the loft, although if I remember correctly,
the filament connections were on pins 4, 5 & 9, giving
you the choice of either 6V3 or 12V heaters)

RTL? Bloody hell, I was already building stuff in DTL in 1968.
