Wow, Roger, didn't mean to tick you off.

I enjoy questions that are easily answered by looking under the covers,
poking around with ohmmeters and voltmeters and signal generators,
and comparing/contrasting small technical details.

So if you say "it wasn't done for reason X", I read what you write
with enough interest to go look and see reason X for myself. Don't
take that as a mistrust of your facts, but take it as me being
interested in what you write about.

If I misinterpret your intended-to-be-factually-incorrect-for-humorous-
intent statements as being actual mistakes, I apologize. 

I do seem to have rubbed you the wrong way a couple times in the past
couple of weeks, putting me in the "bad guy" column way more than
anyone else on this list. Who knows, maybe I'll get kicked off the
list the next time I look under the covers of my R-390A instead
of trusting the word of a respected poster.

Tim.
