Uses DMM as readout. Ability to set a signal to 100kHz is also
required to calibrate.

I've gone all these years without one but I might give this cct a try.
Any idea of the twin screened / coax? cable characteristics, min/max
lengths ?, just cruddy old audio interconnect shielded cable
sufficient ?

Although labelled "Twin Shielded Cable", the schematic is drawn to show
two *single-conductor* shielded cables, one to deliver the test signal to
the cap, and one to sense the response across the cap.
