Our JJ 5881 Singles, Matched Pairs & Quads are rich sounding valves. All valves tested in0house with the matching process performed by hand for the best possible quality. We also have these valves factory matched and we refine the process. Includes a certificate with the matching results. We test using voltages found in amps.
The  5881 Matched Pairs from JJ Electronic are a pair of 23 watt tubes and rated for a maximum plate voltage of 400Vdc. The 5881 first entered the market 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’s also critical to re-bias the amp, heeding the 5881’s 23W rating. This will provide a vintage tone and 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 is not covered by warranty.
The JJ 5881 is an excellent value for the money.
We have shipping options for UK and international customers.

Includes a 180 day from receipt warranty (excluding user-caused mechanical damage) for peace of mind.

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.
