   Sounds like an ordinary old wax paper condenser, definitely not   
   polarized.  What's its function in the circuit?  Sounds like a real   
   home-brew mod, as if it is grounded, the band (outside foil) should   
   have gone to ground.  An ordinary .05 mike mylar cap, 150 volts or higher,   
   is a replacement, if that value is suitable for the circuit function.
