>2. Are DUD poly caps common?
This one of the things Bob Pease warned about many years ago. Yes, there
are dud polystyrene caps. I had a batch of bad 470 pF units -- it took me
years to figure out why I just couldn't get some circuits to work. At one
point I tried replacing the cap and that was the problem. It really
doesn't make sense to use polystyrene any more. C0G or NP0 ceramics work
just as well, if not better.
