  • There are some important things to know about the reissue Tungsol 5881 tube before you decide to use it. The Tungsol 5881 is a 23 watt tube and is rated for a maximum plate voltage of 400Vdc. The many amplifiers that have higher plate voltage but use a tube rectifier can use the Tungsol 5881 tubes 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 Tungsol 5881 in a high voltage amp with a solid-state rectifier, will likely cause problems and are not covered by warranty. For these cases consider the Tung-sol 6L6GC-STR tubes instead. They are rated for 30 watts and 500V so they will hold up better. Their tone is quite similar to the 5881 too.

    From our review of this tube: "The Tung-Sol 5881 tube may be the best option available for guitar toting tone freaks. The magic is definitely not in the name. The new Tungsol 5881 tube has it all going on. The pair I evaluated has been seeing steady gigging use for about 8 weeks. In this case, about 20 hours a week in a 1964 Fender Bassman running flat-out. One tube has drifted about 1ma, but that's after 150+ hours of full power usage. The tone is everything you would expect from NOS for about 1/3 of the price. These are full spectrum bottles that deliver everything from the classic, deep, "piano-like" lows to crystal clean highs. They are very tolerant with regards to biasing; allowing anything from 50% - 70% of rated plate dissipation to be dialed in at idle while still producing great tone. The construction differs slightly from the NOS in my possession but they are very close. Microphonics has not been an issue at all; no ringing, pops, ticks or squeals - unless you create them with a guitar. The overdriven tone is thick but articulate and just gets fatter the harder they are driven. Dime your amp and then use your guitar's volume and tone controls to dial in just about anything you want."
