The secondary gave 30 ohms but the primary
showed infinity. Is it easy to find this part or do I have to find another 42-321.
Thanks
I would wind 50 or 60 turns of sm magnet on the coil form like 36ga wire. It's untuned so it not super critical. Or you could use a rf choke in place of that winding and use a small mica cap like 50pf from the plate of the rf amp to the input grid of the mixer tube.

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
