[R-390] Capacitors - Testing and identification.

[Paul Galpin]

Hi guys!

Two questions, relevant to R390s and other sets

1. When I replace a capacitor, I test it by putting it across my 500V Insulation tester. Only if it comes down to infinity do I then
put it into the receiver. What is the general opinion of this? Is it adequate (for safety, of course, not capacitance value)

2. Everybody in the States seems to know what are Orange drops, BBODs, metallised foil, etc, etc. Over here in RSA, we don't seem to
have those ranges and certainly not down here in Port Elizabeth.  
But we do have second hand capacitors. Where could one get pics of these things to help ID the different sorts?
