Harmonic Mixer in W6TC's HBR receivers..
 

I am thinking of using a 6ES8 in a Pullen mixer for a HBR
receiver project. Ted used the second harmonic of the LO
for the bands above 7 mc. I'm wondering if the Pullen
mixer is suitable for this sort of LO scheme? The original
design used a sharp cutoff pentode in the mixer with light
capacitive coupling for LO injection to the grid. I had hoped
to used a balanced mixer, but it is entirely unsuited for this
application. Any advice on the Pullen's suitability?
