[Amps] Drake L-7 Linear capacitor

[Harold Polk]

I have a Drake L-7 linear amp that has blown the "printed circuit 
board" capacitor C-41, the one that is across a RF choke, RFC 4.  I 
think the part is not available anymore and was wondering if some other 
commercial capacitor could be substituted for this "home made part".  
If anyone knows of a replacement for this cap I would appreciate 
hearing from them, especially the voltage rating of the cap.  The value 
shown on the schematic is 47pf.
Of course it took out the "fuse" resistor in the P/S and that part is 
relative easy to obtain, a 0.82 2 watt resistor.
Thanks
Harold
