Thanks for the tip, Jim! That did it and now we're working once again. It
took a little brain surgery to get into it but it was obviously a cold solder
joint from the center tap and the lead coming out of the secondary! I just
hope Murphy stays away during the next contest!
Thanks again,

"dig" the center tap out of the transformer and re-solder it. You may have to
peel some paper back to do it.
Give it a try!

Hello all...A couple weeks ago I posted a message to the group about losing my

an annoying problem to find!!!
