1. Capacitance Meter? Be a _REAL_ Radio Ham by making one?

2. ISTR that C = nAe/d where n is the number of facing
surfaces?

I'd like to know the specs of the variable capacitors used in the MFJ-920
VHF Dual Band Tuner. There are no visible markings on them. They have 6
fixed and 7 moving semicircular plates about 33mm in diameter - spacing
between the plates is in the region of 1mm. I want to recycle into
something more useful - such as a HF tuner.
