Product Description
The 5881 Matched Quad from JJ Electronic are rich sounding valves.. All our valves are tested by us and our Supermatch process is done by hand for the best quality. We also have these valves factory matched and we refine the process. We issue a test certificate with the matching results
The 5881 Matched quad from JJ Electronics are four 23 watt tubes and are rated for a maximum plate voltage of 400Vdc. The 5881 was introduced to the market back in 1954.
The many amplifiers that have higher plate voltage but use a tube rectifier can use the 5881 Matched Pairs from JJ Electronic without issue. A prime example is the ’59 Bassman LTD. However it is also critical to rebias the amp heeding the 5881’s 23W rating. This will provide a vintage tone and less clean headroom. Leaving the bias set to a 6L6GC setting and/or using the JJ 5881 in a high voltage amp with a solid-state rectifier, will likely cause problems and are not covered by warranty.
The 5881 Matched Quad from JJ Electronic offer excellent value for money with an awesome sound

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
