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.

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 called shortly after ordering some replacement valves as I wondered if there was anything else I needed to address the noise. Not only did Stewart suggest a more suitable valve for the tone I was after, we had a really enjoyable chat and he give me some really useful tips for future fault finding. Follow your nose and shop here folks, you will not be disappointed!!." - Colin W July 2019.
