[Boatanchors] Measurements Corporation Model 80 Signal Generator(Boonton, N.J.)

Hi Morris,
    The model 80 is one of the classics, and still a good one.  I've had
one, but not for about 10 yrs now.  I'm not sure if you're needing a whole
"trombone" pad assy or just some cable to move it.  I've got some small
dia. stainless cable, if that'll help let me know how long a pc you need &
I'll go find it & get some on the way to you.

I just received one of these from a fellow boatanchor fan and was excited
that I might get it to work at refurbishing some of my old gear.  Upon
opening it, however, I find that the output pad cable is mostly gone and
someone has tried unsuccessfully to solder it back together.  The pad
control, a cylindrical arrangement, appears to be a critical part.  The
core
of this pad is to be pulled back and forth by the cable.  The cable,
broken
now, normally connects the front panel vernier/knob combination which is
labeled "pad" with the sliding core of the cylindrical device.  There may
be
more pieces which are missing or broken.  (No manual available as yet)  I
am
guessing that this part is some kind of capacitor for loading or tuning
the
output.

This is a beautifully made piece of gear with two large meters for showing
percent modulation and some kind of null indication.  There is an
ingenious
turret arrangement, shielded by a large round canister, which is used as a
band switch.  It appears that this was once a very accurate signal
generating device and it would be a shame to part it out too quickly but I
am not sure as to how likely I can find a replacement part.  I will hold
on
to it in its present condition for a couple of ham fests just in case.
There are also about 10 electrolytics that will definitely need
replacement,
some of which are 600 volt.  I would expect that the usual practice of
series caps would not work well here to reduce the voltage requirements
due
to the construction of the unit.  Does anyone have an opinion on the
likelihood of a replacement "pad"?
