Thanks for looking at the video. I just received an email from another Flexer
who is seeing exactly what I'm seeing on his system. Any suggestions on what
else we should look for?
I hear the tone loudest when the preamp is off.
Thanks for the many suggestions that I've received so far!Edwin MarzanAB2VW>
