Here is (1) one brand-new and never used, new-old-stock/new-in-box (NOS/NIB), Jennings Type UCSL 750 Vacuum Variable Capacitor. The published specified capacitance range is 5 pF to 750 pF, and it is rated at 5000 volts, maximum.

Per the factory test tag affixed to this capacitor, the Jennings-measured capacitance range is 4.5 to 753 pF.

As you can see, this capacitor is packed in the original Jennings box, and it has never been used. I believe this is the first time the box had been opened since the capacitor left the factory, and I only opened it to shoot these photos.  Note that the original factory protective foam rubber packing had deteriorated from age, and I have discarded it as a result. It has been replaced by new 1-inch bubble-wrap for safe protection during shipment. 

As with all electronics of this vintage, this item is sold as-is and with no warranty. Please look at the accompanying photos carefully; what you see is what you will receive, and feel free to e-mail me with any questions you may have!

Please be sure to see the many buyer positive feedback comments I have received as a seller here on e-Bay. Bid with complete confidence, as I have 100% perfect positive feedback, and I have been a member of e-Bay since 1999!
