A 41-638 pF, 1 kV variable capacitor, part number Mignon (The Reynolds Co), is on offer. The unit is in good condition with some scratches, dirt and wear; it will need some cleaning before being put into service. The 0.25 diameter inch shaft turns easily and exhibits no slippage. There is a 0.25-inch shaft on one end.

There is a fine adjustment knob that is slightly bent. Also, the rubber material that moves the fine adjust mechanism is rotten and will need to be replaced. See photos.  

The capacitance was measured with an Extech 380193 LCR meter. The distance between plates of opposite polarity is about 0.031 inch. The peak operating voltage (1 kV) was estimated using data from Radio Handbook, 20th Edition, William I. Orr, W6SAI, 1975, pp. 11-30. The user is encouraged to verify the peak voltage data before placing this device in service.

The 41-638 pF, 1 kV variable capacitor, part number Mignon (The Reynolds Co), shown in the photos, is the only item included in this listing. No cables, accessories or test equipment are included. Any test equipment shown is to demonstrate the operation of this device. The photos were taken on a 1 cm grid. I will combine multiple items together to reduce shipping costs and will mail one or two business days after receiving cleared payment.

Questions are welcome. Thanks for stopping by!
