Sylvania 6SL7GT Short Chrome Dome Gray Plate Well Matched (10%) Single NOS 6SL7

This is a well matched pair of Sylvania 6SL7GT vacuum tubes. These tubes were made in the USA by Sylvania, and one is branded Zenith. These tubes test close to each other, well balanced. These tubes were manufactured to rigorous industrial standards, so you can expect low noise and microphonics. These tubes have a short clear glass envelope, round gray plates, chrome domes, and green or yellow lettering. These are highly sought after Sylvania 6SL7GT tubes, act quickly before they sell out!! More available upon request.

Be careful buying tubes from sellers who claim matched tubes without providing measurements or the equipment that they used to measure their tubes.

I personally tested these tubes on my recently calibrated Hickok 600a and my TV7D/U tube testers and the results are as follows:

2,225/2,000

2,050/2,000
