Product Description

The 7868  are compact versions of the 7591 valve and were a later introduction.  They are commonly found in the later versions of Hi-Fi and also in juke boxes. Some Peavey guitar amps use these valves too.

The 7868 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.

If you wish a matched quad then just order two sets. The price shown is for a matched pair.

Note that some of the pairs are in white boxes due the factory running out of printed boxes.  These are genuine from the factory units and are brand new. This is a specialist valve so they are not continuously manufactured.

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 7868’s are Fisher and H. Scott in their home audio equipment. They are also found in Peavey guitar amps. The 7868 is the updated smaller package variant of the 7591

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
