GE 12AU7A Gray Plate Well Matched (5.8%) Pair NOS ECC82 12AU7

This is a well matched pair of GE 12AU7A vacuum tubes. **I have hundreds of pairs available.** These tubes were made in the USA and are an excellent upgrade to current production Chinese and Slovakian junk. They were manufactured to rigorous industrial standards so you can expect low noise and microphonics. Both tubes are very closely balanced. These tubes have short, ribbed gray plates, white lettering, and a halo or horseshoe top getter. These are highly sought after GE 12ATU7A tubes, act quickly before they sell out!! More available upon request.

Be wary of sellers who list tubes that are matched without providing test results or the equipment that they used to test the tubes.

I personally tested these tubes on my recently calibrated Hickok 600a tube tester and the results are as follows:

2,825/3,000
2,825/2,900
