Good rule of thumb is to check the rated capacitance... usually everything below .001uF=1000pF (or mmf if you prefer the old notation) is genuine mica and everything .0047 and up is paper. I typically replace every rectangular cap .001uF and above with film caps. Even true micas are prone to failure in sweep circuits so ordering spares for those for the sake of our mutual friend Justin Case is an advisable measure to take.
