The MF200 was a lucky find at the local tip, especially lucky since the
manager was out at the time and the site employee didn't know these items
(including a function gen & a RF sig gen) were supposed to be reserved for
someone else. Another item in my collection is a HC7030 DMM - my first
DMM, this was rescued from a waste paper basket at a refurb Co I used to
work for, when I got it home the Ohms & AC ranges didn't work, on opening
the case I found the only socketed component was a dual op-amp so I tried
replacing that and "hey presto" that fixed it. The Co even lent me a
multimeter to calibrate it with the presets in the back.

Some old time repairmen can often figure out problems by experience. See if
you can find someone locally.
