1960 CBS 12AX7 12AX7A ECC83 Long Plate Tube, Tested
This has long (17 mm) gray plates, a halo getter and was made in 1960.
This tube was tested on my calibrated Hickok 539C. it has been tested for shorts, gas, and transconductance. The tube tests very strong with a readings of 1400/1300. Minimum is 875.
Tubes are described, tested, and presented to the best of my ability, subject to the limitations of the equipment that I have available (Hickok 539C and several TV-7’s). Test results are likely to vary some between your equipment and mine due to the imprecise nature of 60-year-old consumer-grade test equipment.
About me. I have over 62 years of experience in many facets of electronics design and repair. I have been working with tubes since was a 12 year old child. I am an active ham radio operator and have been for 62 years. I’m a retired electrical engineer with 30 years in the Semiconductor industry. I’ve been collecting, buying, and selling tubes and other tube based equipment since the 1980s. The pictures you see are of the actual tube(s) you’ll receive.
I will ship international.
