[ARC5] ARC-5 receiver mixer mod attached as PDF

BTW, let me make it quite clear that the one-page "article" on the ARC-5 receiver mixer mod 
I sent is NOT, repeat NOT, a Pullen Mixer!

It is simply a standard dual-triode used as a single-triode mixer and a single-triode HFO. It 
is not even remotely like a Pullen.

I would almost bet that used as it is drawn, it will exhibit significant "pulling". There is no 
isolation between the HFO and the mixer sections.
