Re: RCA AR88D Comms Receiver.
It's possible I've met your problem John.
I've now got the Wearite oscillator coils using a brown material working OK but the two highest shortwave bands use transparent plastic (lucite? or perspex?) formers and neither will oscillate.
I haven't tackled these yet but they use small dust cores to tweak their inductance.
Maybe that plastic material is hygroscopic and if reversable may respond to a hairdrier? On the other hand as a last resort I could remove the formers because the coils use substantial wire that should be self-supporting.
