This listing is for a Pair (2) of 6SJ7 Pentode vacuum tubes in the Metal (the glass 6SJ7GT is available via a separate listing) tube shape. They have a black bakelite octal base, hidden plate, and hidden getter. We have RCA Cunningham, Sylvania, Tung-Sol, GE brands in stock. The tubes may not match one another, but they have both been tested good.
Your tubes have been fully tested on a computer-regulated Amplitrex AT1000 on Fixed Bias setting with used good results. It has also passed shorts and gas tests. The tubes might have mechanical wear or have the label rubbed off - these are very old! Tubes that test like new (tNOS) are available in a separate listing. Every tube you receive from Sound By Doc is guaranteed against failure for 60 days after purchase, an industry extreme!
