I bought this new from R.F. Parts awhile back. Never used Oren Elliott Products #73 1 12 53 Variable Plate Tune Capacitor. My meter says 315 uuf but I think its actual rating is 320. Gap is .125" so it should handle 4.5KV. Measures 10 1/16" L x 2 5/8" W and just under 2 1/8" H. Excellent condition. Asking $40 plus shipping CONUS. Reply direct to
