This is an almost perfectly matched pair of Sylvania JAN 6SJ7 vacuum tubes.  These tubes are old with metal bases, and should sound great in your amp. They were manufactured to rigorous military standards, so you can expect low noise and microphonics. They have metal bases, black plates, black or gold lettering, and top getters. These are excellent Sylvania 6SJ7WGT tubes that are highly sought after, 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 the tubes.

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

2,500
2,525
