If you were to use any tubes at all, it would be best to use one tube akin
to the 6be6, hang the oscillator and the product detector ckts on it, and
have the advantage of getting conversion gain instead of loss.

I'd thought of that after I posted. It's easy to lose track of things,
and really, the 6AL5 suggestion was that.

Yes, once you take out the semiconductor diodes, there are better ways
of solving the problem than putting in tube diodes.

On the other hand, it's easier to imagine someone modifying the KWM-2
than the R390, which proves the point of whoever suggested the KWM-2.
