OK I pulled the oscillator coil out to look at it and check continuity.  It looks good in that there isn't any green crud/corrosion that I've seen in some pictures.  The measured values are in yellow on schematic photo.  One value is off - 18 ohms (spec is 2.8 ) but its certainly not open, not sure what's going on with it...thoughts?  The resistor incorporated into the coil assembly is about 11.4K (14% high) and the 710 pF cap is original...perhaps I should try replacing it/them?
