      I think I must make very clear that I was not trying 
to denigrate Bob's efforts at all.  I think perhaps my post 
may have read like that and if so my apologies to Bob, who 
obviously did a lot of work on the spread sheets.
     The coding system for capacitors is a mess and no 
fooling. There are three and six dot systems and the RMA and 
JAN system and variations, not to speak of the stripe system 
as seen on the notorious Black Beauty caps.
     The problem is how is one to be sure of the type of 
capacitor one has lurking around in the guts of a chassis 
like a cockroach under the sink. Ultimately, it doesn't 
matter since they all go bad with time.
