Just curious, for use way in the future. This time it's going to NARCO.

Why on earth woiuld you spend the aggravation sending it to NARCO service.
Take it to whatever avionics shop you like. There ain't anything magic about
the old AT50's. It is most likely a trivial fix. I've had the same thing happen
in planes in the past (spent some time with COS dialing up various numbers
and having them read back what they saw to see what bits were stuck on).


I've also had very good luck with Narco service.
But, for the price you would pay for a repair, you could probably find a
replacement with a guaranty.
You can find cheap 50's and 50a's for sale all day long!
Just my $0.02
