[time-nuts] Heads Up to HP 5371A & 5372A Owners

[J. Forster]

HP is NOT perfect.

I have a 5519A LaserInterferometer head which was acting up. They are
distinctly non-trivial to fix. Anyway, this one had a critical feedback
detector that had NEVER been soldered to the PCB.

Moral:  Look for the simple faults first.
