1nF 2Kv Capacitor

TCC "Cathoderay Visconol-X" capacitors, 0.001uF 2Kv DC working voltage. We believe these to be paper-foil capacitors and are NOT suitable for Tesla Coil use. Capacitance tests within tolerance but no high voltage test conducted. Stud mounting on the bottom and solder tag on top.

High voltage Ceramic pass-through Insulator

Ceramic pass-through insulator rated for continual service at 132 KV and intermittent service up to 400 KV when clean. Has several chips (pictured) which means it would have to be thoroughly cleaned, dried and re-sealed before high voltage use. Yellow bar in the image is 1.2m long. A little dirty from storage but clean up to a shiny brown glazed surface with ordinary non-abrasive cleaners. Owing to weight, this item cannot be shipped, it is only available for collection from Bath or Reading, or delivery within 40 miles of those cities for an additional charge

Linear Xenon Flash Tube

Xenon flash tube, 350mm Long, heavily used and has some debris inside the tube. We were told when we got it that it's rated for 1KJ per pulse but given it's age and heavy use we DO NOT recommend using it as a flash tube any more. When last used it still held xenon and would display a writhing plasma stream when energized by a Tesla coil.

5.5Kv 120mA Transformer

5.5Kv 120mA transformers, NOT neon sign type so will require external ballasting for Tesla coil use. Primary side is tapped for 190-260Vac in 10V steps, 45-55Hz and has a screen option. Transformers are partially or fully resin potted so any sort of modification to the windings is likely to be impractical. Manufacturer, colour and potting style varies but all have the same ratings.
