That trick would certainly make me nervous. In any case, do
two wires shorted together still have a resistance as high
as 0.5 ohm?

I see that now. Indeed, I pretty much started to see it a
while back but was at a loss about how to bail out of a
situation I should have never gotten into. I should stick to
pointing out common-sense issues to neophytes (and writing
introductory books and articles on audio or doing record
reviews) and not get involved with situations that put me in
a bit over my head.

In any case, with all of the turbulence this series has
stirred up I do hope the original poster has at least solved
his problem.

Thanks for the thoughtful reply, Stewart. While it was not
quite as detailed as the longer one submitted Pierce, it
certainly was more civil.
