Product Description

7591S Matched Quad from JJ Electronic are compact versions of the 7591 valve.  Some other makes are somewhat taller than the original 7591 footprints and so the JJ versions assure you that they will fit into your amplifier. You will receive four matched valves/tubes.

The 7591S are pre-matched for us at the factory and are then tested by us and our Supermatch process is done by hand for the best quality. We issue a test certificate with the matching results

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 les or else their working lives will be shortened.

We also offer a 120 day from purchase warranty on the product ( excludes user caused mechanical damage failure and incorrectly set bias ).

Note: Valves use high voltages and these voltages are dangerous. The amp can still retain these high voltages for some time even after being switched off.  If you are not sure of fitting them , please seek the services of qualified personnel

"I don’t think I’m the only guitarist out there who knows his/her guitars, but very little about tube amps. I ordered a Supro valve kit (which is great), but it’s the service, help & advice I received from Stewart that was outstanding. I was going to say ‘these guys’, but it didn’t seem right, as my communication was just with him. Thank you!" - Robert G.
