Listers,
The old Terra TXN 920 has mechanical frequency selection by tiny pushbuttons
above and below each digit. One digit does not change properly in either
direction. The 2 buttons are stiff and the number usually moves only 3/4 of
the way to the next digit. One com digit is also difficult but it changes
fully with a little jiggle of the pushbuttons.
There is no access to the switch mechanism or contacts without major
surgery.
I'm looking for some experience with this problem. Should I try to get some
silicon spray or Corrosion-X/ACF 50 into the switch? Other ideas?
Thanks,
Mike
