Hi Don,

I have some teflon insulated wiring that has been in place for years.
Apparently the memo about how awful teflon is wasn't out and that wiring
doesn't know any better than to work. Maybe those other products are
better choices in new applications today.

Maybe the post about the lead length came from somebody who didn't know
these caps are not being used at UHF. At power and audio frequencies the
inductance doesn't amount to anything at all.

73,
