The Tung-Sol 5881 has a lovely rich tone, offered here as a matched quad. Made in Saratov, Russia.
Tung-Sol was the originator of the 5881, and has carefully recreated the classic as the brand new Tung-Sol 5881.
The Tung-Sol 5881 is a 23 watt tube rated for a maximum plate voltage of 400Vdc. The 5881 first hit the market back in 1954. These valves sound wonderful in Marshall JCM 900s, which were specified to use 5881s.
Tube-rectified amplifiers that have higher plate voltages can use 5881 tubes 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. A superb choice for vintage tone and less clean headroom. Leaving the bias at a 6L6GC setting and/can cause overheating problems and is not covered by warranty.
We test all our valves in-house here at VTGA on our suite of AVO and custom-built testing equipment to ensure the best possible quality. Tests at real amp voltages and includes audio listening tests. We send each order with a certificate showing the test results.
Includes our 180 day warranty.
