I thought 'pulling' had as much to do with difference between signal and HF osc. as AVC voltage. I think 
'pulling' occurs even without a signal, doesn't it, as you for example, change the RF antenna trim control ? 

Interesting article. I have been saving such articles and schematics of receivers for years, mostly still 
puzzled about AGC circuits in the conversions. My preference would be to use tube-base plug-ins. 

Ben, did you publish your procedure with the Trio receiver? 
I would love to see that too.

I bought a couple 'transistor conversion manuals' from a fellow who has some videos on Youtube. I do
have some differences though. I see no need to patch in a new power supply  when there's already one
right there. And I see no need to use a whole lot of 2.5 mH RF chokes. Nevertheless, I consider my money
well spent when I get some information and perhaps gather some new ideas.
