Transmitting Variable Capacitors

These variable capacitors are ideal for a tube high power power amplifier or high power antenna matching unit. I’m asking $180 for the lot which includes shipping to anywhere in Canada. Buy them for your club and spread them around. A sensible offer will be considered. See the photograph:

Item 1: Marked Hammond 3000V 350pf, but measured at 270pf. I suspect the back plate may have been replaced at some time in the past.

Item 2: Marked Hammond 4600V 355 pf; measured 335pf (close enough)

Item 3: Marked Hammond 1500V 500pf; measured 505pf.

Item 4: No markings, measured 260pf; estimate 3000V

Item 5: Marked Hammond 3000V 350pf; measured 350pf

Item 6: No markings, measured 150pf; estimate 4000V

Item 7: No markings, measured 115pf; estimate3000V

Item 8: Marked Cardwell, measured 50pf, estimate 5000V.
