[Milsurplus] PP-4763A Power Supply Bridge Diodes

[WA5CAB at cs.com]

Dunno about the 35 amp rated diodes.  Actually, three (PP-4763) or two 
(PP-4763A) of them are 1N1186AR's or 1N1186R's.  The PP-4763 is actually rated 
at 60 amps continous but has no appreciable surge rating.  It wasn't built to 
operate dynamotors or inverters.
