[Boatanchors] Question about capacitors

Mon, 15 Mar 2004 07:11:18 -0500

In the absence of an opinion from someone who may have first hand knowledge
you might just check them.  If all you have is an ohm meter you would look
for a reading of infinity after a bump to charge the device. Be sure to clip
to the leads because your hands will show a high resistance if you're
holding both meter leads.

You could also sacrifice one of the units to determine what the dielectric
is made from.

You might find an audio guy who thinks these things have magic properties
and trade for modern. If so let your conscience be your guide.

Unless I had a very large number of these I believe I'd just use new Mylar
or other plastic film types. They are not all that expensive if you shop at
MCM, Mouser or Digikey. You don't need genuine "Orange Drops" but they are
fine if you want to pay the extra price. I bought in lots of 10 several
common values so the price per cap was relatively low.

Subject: [Boatanchors] Question about capacitors

Hello to the group,

We all know about the dreaded Spraque BBOD's.  Is the same true of Cornell
Dubilier?  I found some NOS Cornell Dubiliers in the bottom of a box of
other
stuff I've had for years and am wondering if they are any good.

Thanks,
Ron, KB0WAR
