The JJ 5881 is a rich sounding valve from JJ Electronic, available here as singles, matched pairs, and matched quads. A 23 watt tube and rated for a maximum plate voltage of 400Vdc, the 5881 first entered the market in 1954.
All valves tested in-house at real amp voltages 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.
Many amplifiers with higher plate voltages and a tube rectifier can use the JJ Electronic 5881 without issue. A prime example is the ’59 Bassman LTD. However, it’s also critical to rebias 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 not covered by warranty.
Quality valves made in Slovakia. The JJ 5881 is an excellent value for the money.
Includes a 180 day from receipt warranty (excluding user-caused mechanical damage) for peace of mind.
