These RCA JRC-5814A tubes test:

90-88/56

88-92/56

89-92/56

91-89/56

on my TV-7D tester (calibrated 1/27/24). Brand new tubes should test 86-86/56 or higher. Tested for shorts, emission, gas and noise.

The 5814A is a military equivalent of the 12AU7/ECC82. They have 3 micas and additional support rods, black plates and square getters. They are closely matched and used with plenty of good remaining life. Their branding is partially worn off; unfortunately.

I do not accept returns unless the items are not as described. Please look at the pictures and ask me any questions BEFORE buying anything.

I’m in the process of listing thousands of tubes. If you want something in particular message me to see if I have it. Thanks!
