Sometimes the plates are bent during initial calibration to
linearize the? scale or hit calibration points within the range.?
Some people "straighten them out" because "someone" had to bend
things out of position.?
Unless you specifically know that someone has re-bent the plates
on the capacitors, I'd suggest leaving them alone.? The plates may
be bent to make it accurate.
All the above is invalid if someone has made adjustments with a
small hammer.

There’s really no reason to check the capacitance
of the frequency tuning capacitors. If some of the plates are
significantly bent (but are not touching), the oscillator will
still work but will be inaccurate. With power off, you should be
able to check across the capacitor with an ohmmeter and get
infinite resistance (an open circuit).?
OK, thanks
They look clear of debris. Is there a way to check their
capacitance or resistance easily ? I have an LCR meter.
