You are bidding on a single 1958 Amperex 12AX7 ECC83 Tube.

This tube has long (17 mm) gray plates, copper support rods, a foil getter and was made in 1958 in Heerlen, Holland. 

This was tested on my calibrated Hickok 539C. It has been tested for shorts, gas, and transconductance. The tube tests very strong with a reading of 1600/1500. Minimum is 875.

All tubes are tested on my calibrated TV-7/B or on my calibrated Hickok 539C. All of these tubes have been tested for transconductance, shorts, gas, leakage and life. All tubes meet or exceed manufacturer published specifications of transconductance (Gm) for the specified tube type. All tests are tested twice - prior to the listing and prior to shipping.

I have been selling tubes on the internet since 1998 and have been working with tubes since the early 1960's.
