One, Cardon C-585, mesh plate 50, #50, UX-250, CX-350 eq - $1,099 - (Whippany, NJ)

One, Cardon, C-585, with the globe/balloon shaped glass envelope. The Cardon C-585 is an electrical equivalent of the 50, UX-250, and CX-350 tubes. Tested on a Hickok TV-3 military tester that has been calibrated. Engraved base, mesh plate. This is the standard by which all other #50 tubes are judged. Firm base, excellent silvering that does not seem to show any wear at all- this tube may well be unused. Tube tests at 1900 where pass/fail is 950 micromho. This is as nice a specimen as I have ever found, it may be unused. Many other lots of tubes for sale this week. Shipping is free within the continental US. Elsewhere- exact postage only, no packing fee.
