I've had good luck watching eBay. You'll be very lucky if you find 
the original Polar or Millen (although one or two have shown up 
there) but the standard FM radio 3-gang caps are real common. They're 
about 25-27pf per section and will work just fine. I see the TRW 3-
gang FM radio caps pretty often on eBay.
