[Boatanchors] BA Resistors

[Al Parker]

Hi JT,
    A quick generalization -- if it was made since 1960 or so MAYBE you can 
re-use carbon comp resistors.  If older, PROBABLY not, they probably have 
drifted high in value, often %20+    NOS stuff in the same age ranges follow 
the same general rule IMHO, I have many NOS carbon comps, some back to the 
1940's I suspect, I keep them for some strange reason, occasionally will use 
some as a temporary load, rarely find one within %10 of nominal, but if I do 
I will give it some warmth a few times with a soldering iron and recheck if 
there is some reason I want to use it for a 'real' application.  Usually the 
latter example is just the stuff made since the 60's.  YMMV
    Overall, if you're stripping something that old, don't take the trouble 
to save the carbon comp. resistors.
