38-1 code 121A
#10

A slight variance in the schematics:  Schematic # 84 (code 121) shows a .05uf, part # 30-4177. What I have in there is a .002 @ 1000v. Oddly, this condenser (original, as it was buried under a bank of resistors, and looked untouched) is ALSO part # 30-4177(P), as is written on the condenser itself.   Question:  Since I didn't get a .002 @ 1000v (as there is no .002 on the schematics) when I got my new parts, should I stick the .05uf @ 630v in it, or just put the old .002 back in it- (it lays squarely at .002 on the meter)?  NOTE:  Out of 25 components I've changed so far, only 2 resistors have been out of tolerance, and only by about 30%. ALL other resistors have been within 10% tolerance... ALL capacitors have been dead on the money so far Icon_exclaim  I feel kind of foolish for "fixin' what aint broke", but I know all these should be changed, for safety's sake.  Icon_mrgreen
