Hi Carl,
For the 565 platform, I agree that is worthy of consideration.
For the 566 platform, I thought (perhaps incorrectly) there
was a pin design change so help reduce that from repeating?
So yes, by all means do what Carl suggests BEFORE packing it
up to TT for their review.

Sounds like the classic "clean the connectors behind the front panel"
problem to me. There's a few connectors that over more than 100
connections and because Tentec did not use gold pins, they need to be
cleaned once in a while. Because there are so many connections, almost
any symptom is possible. But the key is the problem starts out
intermittent.
Remove the front panel, get some good contact spray, unplug the
connectors, spray them, then plug them in and out about 10 times to
clean them.
