Pondering the situation, before I rewind the failing detector coil, I am curious if anyone has substituted a similar new/NOS coil with similar inductances. I measured mine I think it's one to four ratio 1.3mh to 4. something. So to reason a new old stock coil should give acceptable results, many on ebay and such. The oscillator would be more difficult, but any of the two section coils should be replaceable. The amp section on this unit is fine, what it's pushed with is failing.
Edit- Should receive 30 AWG Essex wire tomorrow. Will start with the oscillator coil as it was crumbling also. Don't know yet what to use for pri/sec dielectric, studying up on coil Q and different materials. Painters masking tape possibly, blister pack, don't know if it makes much difference at the broadcast band, will see what happens. Also an Eico 324 should be here soon to align it if all goes well, use to have TV/fm sweep and 20mhz scope, but sweep did not go to the lower KC if I remember.
