This is a matched pair of RCA 6SL7GT vacuum tubes. Both tubes have the RCA logo or factory code printed on the base, and one is branded Bell & Howell. These tubes test very close to each other, both balanced and matched. They were manufactured to rigorous industrial standards, so you can expect low noise and microphonics. These tubes have clear glass, round black plates, bottom getters, and white lettering. These are highly sought after RCA 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:

1,650/1,875
1,875/1,900
