Bought two 1200 pf 4 kV for use on big 160 antennas out at N4AF, from QRO-stuff. No problems and have done the job out in remote box for seven or eight years now. Very stable. Quite large, drive shaft is NOT 1/4, 12mm or almost 1/2. Most likely have to fabricate a knob or reducer.
Those big things are the final answer, absent direct lightning strikes, for going the distance QRO. Prices for Jennings brand new retail are simply awful new, but on eBay the Russian listings are affordable. This is most like what we bought: http://cgi.ebay.com/Vacuum-Variable-Capacitor-10-1200-pF-4kV-New-Box-/200563805228?pt=LH_DefaultDomain_0&hash=item2eb288cc2c#ht_2455wt_1139 73, Guy.
