1960 RCA 5814A 12AU7 ECC82 Command Style JAN Mil-Spec Tubes, Matched Pair, High Testing, Matched Codes

1960 RCA 5814A 12AU7 ECC82 Command Style JAN Mil-Spec Tubes, Matched Pair, High Testing

These tubes have black plates and halo getters. They have matching 1966 date codes. These tubes have identical construction to the RCA Command tubes.

These were tested on my Dan Nelson calibrated TV-7/U. They have been tested for shorts, gas, and transconductance. The tubes test very strong with readings of 93/98 and 95/98. Minimum is 56.

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.
