Re: Improving Selectivity In Vintage Receivers
I think that might be a fair way to start. The emitter and collector positions might be good places to try adding single ceramic resonators if that's what you have.
If you have 3 or 4 terminal filters then they would probably be better in series with (or in the place of) the IF gain control. I suspect you will need a terminating resistor though and watch to block any DC in both these scenarios!
Sorry still no results for Murata SSB filters. You know who's law says I have lost it...grr.
