7591A Tung Sol Matched Pair is reputed to be the best re-creation of any 7591.
The 7591A Tung Sol Matched Pair are pre-matched for us at the factory and are then tested by us on our suite of Avo testers and our Supermatch process is done by hand for the best quality. We issue a test certificate with the matching results showing the tests at real voltages found in most amps
The original 7591 valve was introduced in 1959 and is a high power valve that is a designers’s dream as it is so easy to work with. As a result, it is found in many home audio products during the 1960’s. Example companies using 7591’s are Fisher and H. Scott in their home audio equipment.
It is extremely important that the bias is set correctly on these high power valves or else their working lives will be shortened.
