Description

These RCA made 12AX7 tubes test: 48-49/32 48-47/32 on my TV-7D tester (calibrated 1/27/24). Brand new tubes should test 49-49/32 or higher. Tested for shorts, emission, gas and noise. These are branded Lowrey Organs and the manufacturer’s code 274 is RCA. Dated the same July of 1958. These came from a 1950’s organ, which is good because tubes for organs were specifically selected for low noise and microphonics. They have tall black plates and angled D/Square getters. The printing on these is very delicate; be careful when handling! 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!
