I decided to delve deeper into the mystery. Here is an .asc file of the strange circuit previously under discussion. https://app.box.com/s/cwlnjt5zh14ubdaul4odvhcehw2tnapa Unless I have made an error, it appears to be non-functional. I am now preparing a bonfire for my collection of such old documents. Robert Miller

This makes sense. Tell us more! Generally in those days radionics amps were what looked like RF amps but with all tuning removed. In that case input coil would be the pickup probe (However here it does seem tuned) but I'd expect output to go to a "stroking plate" rather than another coil.
