What's the temperature stability of the D/A?
How does that compare with a 10 turn pot? I remember a comment about pots
aging. It was somewhat recently. I don't remember the details. I think it
was something like the wiper wore a small groove which made it hard to make

A possible option is to just measure the osc and do the adjustment in
These are my opinions. I hate spam.
