Speaking of Wavetek 3000's:  They are choc-O-block full of
axial leaded electrolytic capacitors made in Mexico.  Sad to
report that they will most all be bad at this point.  Their
failure is in the rubber seal for the positive terminal.  It
allows the capacitor to dry out rendering its bulk capacitance
null and void.

Electrolytic capacitors marked "Mexico" reached the replace
on sight stage a good 20 years ago.

The trimmer caps on the reference aren't generally a problem.
