All,
When I made the post, I intended and asked for everyone to contact me off the
list as I figured some wouldn't like it. Dave couldn't reach me through his ISP
to mine, and this mailer was the only way he could reach me. I think I answered
3-4 questions which was posted on here rather than sent to me off the list, and
the others that came in I sent them back private. The few I answered on here
was needed to clarify what I said before everyone. Any after that was sent
private. It was not my intent to continue the discussion here, if some would
like to read my original e-mail. I will quote for the admin what I said, " If
any are interested, please contact me off the list".
The rivetnut deal, was an important issue about 1 week back and nothing was
said. The use of rivetnuts for homebrewing amps can make assembly much easier
and was why it was originally posted.
