Sylvania Made For Baldwin 12AU7A Long Gray Plate Well Matched (5.4%) Pair NOS 12AU7 ECC82

This is a very well matched pair of Sylvania JAN 12AU7A tubes that were made in the USA. The tubes were manufactured for Baldwin Organ Company, which means they were specially screened for low noise and microphonics. Each of these tubes tests closely to the other, and both are visually almost identical. These tubes have long gray plates, green lettering, and a halo top getter. These are highly sought after Sylvania JAN 12AU7A tubes, act quickly before they sell out!! More available upon request.

Be careful buying tubes from other sellers who list "matched pairs" but do not provide test results or specify the equipment that they use to test their tubes.

I personally hand tested these tubes on my recently calibrated Hickok 600a and TV7D/U tube testers.

The test results are as follows:

2,700/2,775
2,700/2,625
