[Test-Equipment] Need schematic for Heathkit IM-28

[Bruce - KB6LWN]

Just obtained the above unit and found a dangling
capacitor inside.  I believe I know where it connects,
but want to be sure b4 applying AC.  Also would like
to have an OEM probe for this unit if anyone has one.

Also, still looking for a Boonton 91CA connector, lead,
and probe(s) - anyone have one they can part with ?

Thanks,
         Bruce
