I bought one of these fine instruments on EBay and have set it up on the bench.
works when measuring something without much reactance, but the main tuning
(C3) is very noisy at many points throughout its range of adjustment. The
capacitor (C4) is quiet, and so are both adjustments of the resistive leg. I
have a copy of
the manual, and it looks like it's a bear to take apart and put back together.
Any ideas about how I ought to attack this? Are there some common things that
wrong? Precision mechanical assemblies are not one of my strengths, so I'm
open it up without knowing where to go from there (and that it's worth doing).
