Default Re: Improving Selectivity In Vintage Receivers

@ jon the only ceramic components I have are the one or two element ones, so I guess those are resonators rather than true filters.

Re moving the coils, I think the former is polystyrene and that does not have much chemical resistance to solvents other than perhaps IPA. I would be be reluctant to start re-arranging 80 year old Litz wire. I suppose you could wind on the outside, but then the problem would be re-using the existing screening can.

@andrew I'll PM you with my email and perhaps you could send the sketch to me and I'll find away of getting on the forum. Thanks.
