The Tung Sol 7591A is renowned as the best sounding and most faithful recreation of the classic 7591 valve.
Tung Sol 7591A Matched Pairs and Quads are pre-matched for us at the factory and then retested in-house on our suite of custom-built and AVO testers to ensure maximum quality. We issue a test certificate with the matching results showing the tests at real amp voltages.
Introduced in 1959, the original 7591 valve and is a high-power valve widely regarded as an amp designer’s dream since it’s so easy to work with. As a result, many home audio products from the 1960s center on the 7591. Companies using 7591s in their home audio equipment include Fisher and H. Scott.
Includes a 180 day warranty.
NOTE
Please make sure your amp’s bias is set correctly. If not, you could hamper your tone and even limit the life of the output valves.
If you’re not qualified to work with high voltages, please talk to an amp tech who can fit your new valves.
