Autocontrol IIIb - great shop in Florida?

[Aviator305]

My Autocontrol IIIb autopilot has become increasingly more erratic over the past few months. The problem started as momentary sharp right or left turns followed by proper course tracking after a few seconds. This happened once or twice over a 7 hour cross-country VFR flight a couple of months ago, so the autopilot was largely usable over that period of time back then.

Now, it will track a course or heading for only for a short period of time (seconds to minutes), and then it will initiate a sharp turn either to the right or left (mostly to the right, but that may or may not be coincidental and/or relevant). If I do not turn off the autopilot, I get the feeling that it would let the plane bank completely 180 degrees to my doom!

Does anyone know of a great avionics shop in Florida, preferably south Florida, that knows this specific autopilot well? I would rather travel a little (or a lot) far to get the problem properly diagnosed and fixed than have someone local misdiagnose or fix things that really don’t need fixing.

Thanks,
Juan
