Default Re: Clarke and Smith 8812 FM IF transformer

If one of the coils is still tuneable, use that as the anode feed for the mixer. Add a grid leak resistor to the following valve, 100k or so, and couple the anode of the mixer to the grid of the IF with ceramic 50pf or so.

Worth a try, at least.

If the set does AM too, dual frequency IF, this probably won't work.
