GE 5751 Black Plate Triple Mica JAN Mil-Spec Tubes, Matched Pair, Tested

GE 5751 Black Plate Triple Mica JAN Mil-Spec Tubes, Matched Pair, Tested

These tubes have triple mica construction, black plates and D getters. They have 1957 and 1958 date codes.

These tubes were tested on my calibrated TV-7/U. They have been tested for shorts, gas, and transconductance. The tubes test very strong with readings of 46/44 and 40/40. Minimum is 32.

They have been sonically tested in my homebuilt pre-amp and are dead quiet with no microphonics.

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 I was 12 years old. 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, and have been a Reverb seller since 2020. The pictures you see are of the actual tube(s) you’ll receive. 

I will combine shipping. Just ask.

I will ship international.
