Hi group,
Just wanted to let you know that I have finished the repair/alignment of my
RA6790GM. As it turns out, the A2 mixer FETs were fine (thank goodness) and
it was a combo of the A2 alignment and the main IF, A4 alignment being off.
I used both the alignment instructions from this web site reference section,
plus some info emailed to me from Frank. Thanks for your help Frank, and
others. It's back in the rack and working perfectly.
I have found reference to an article written in 1995 by Dallas Lankford
regarding a noise blanker circuit he designed for the 6790 using an Allegro
Micro chip. Does anyone out there have it and could you please email it to
me if you do? I would like to look at it as one of our neighbors has just
installed an electric fence....you know the kind that goes tick in the
night. :-)
Thanks again for all of your help. It's a great group.
