There seems to be a good supply from the vendor as they are currently listed as: <javascript:;> * <Javascript:;> * <Javascript:;> <http://cgi5.ebay.com/ws/eBayISAPI.dll?SellLikeItem&_trksid=p2047675.l2567&r t=nc&item=271275539786> 2 200 pF 10kV LOT OF 2 HIGH VOLTAGE CERAMIC DOORKNOB CAPACITORS KVI-3 (???-3) Shipping took only a week and the items fit inside the tuner easily. I used some tinned solder wick to make the connections to the switch as I did not have any tinned braid available. Herb Schoenbohm, KV4FZ.
