A few months ago I bought an HP 8647A signal generator that had the
plastic shaft of an optical encoder sheared off at the bushing. I had
to take the encoder apart and graft an aluminum shaft onto the stub of
the plastic one. To my amazement, it worked!

If it's the one that I think it is... look closely at the photo.
The shafts on two of the pots are sheared off at the panel. These
are the display update control and the external arming level
control. These were custom HP pots with a funky (and delicate)
switch. They had brittle plastic shafts. Gee, how do I know
this... could it be that a large percentage of the 5370's for sale
have the same defect?
Luckily those controls are not too critical for normal operation.
They can be replaced with regular (switchless) pots if you jumper the
switch pads correctly. Be careful, there were two different layouts
to those controls.

So exactly how did you know that I bought a (cheap) 5370B a few hours
ago on the e-place
