Yes that's absolutely true, that's why you typically don't muck with the cap type in the front end, the key being RF frequencies, figure 100MHz for FM. Now once you hit the IF stage the frequency drops to 10.7MHz and then into the composite stage at about 55KHz which is where C3 lives, so no there's no good reason to use a ceramic there. More a cost and availability reason than a technical reason. IMHO

I see you put a poly cap at C15 on the MPX board. Besides that location and C3 are those the only locations you feel benefit from a film cap upgrade? I was curious where C15 was in the signal path?
Hi sherod,
C15 is part of the stereo switch filter, and on mine it was already a film cap. I did check for value, should be the same on yours.

...just as what is in the deemphasis. I haven't checked for value but was wondering if that location was critical for the sound.
No, not at all.

I have some polystyrene caps on order to put in that location.
