New Plate Current Tested Psvane 5881 / 6L6GB Hifi Vacuum Tube

Psvane is famous for their reliable and great sounding tubes and this 5881 is no exception. Fit for any audiophile's high-end needs or any tone-chasing guitarist's amp. 

A fresh take on the classic 5881, Psvane leaves its mark with high quality construction and sound. We say fresh because this tube is electrically somewhere between a 5881 and 6L6GC. These are rated at the standard 23 watts of plate dissipation. However, they can take up to 450 volts on the plates and many have found them to be stable even above that. The normal 5881 is essentially a baby 6L6. The 6L6GC is rated up to 500 volts on the plate but most amplifiers don't run them that hot. That means that this tube should work in 90% of circuits that call for a 6L6GC which is not true of any other 5881. If they don't work for you, we'll gladly accept a return. Given that the 6L6GB is simply a less powerful 6L6GC we're calling it the 5881 / 6L6GB.

Guitarists - if your looking for early breakup, here is your answer. And for the audiophiles, this tube provides extra headroom and clarity in circuits that call for the 5881. 

Note - These tubes are about as tall as a typical modern 6L6GC. The 5881 is usually a short tube so they may not fit vertically in certain amplifiers. 

Testing and/or Matching

Tested and/or matched at full operating voltage on a Maxi-Matcher tube tester for both Ip (Plate Current) and Gm (General Mutual Transconductance). We always TRY to match by 5% when we can (90% of them time) but our cut-off matching parameter is +/- 15%.

A special note on factory matching

Psvane tubes are frequently sold only with factory matching or in proprietary Psvane packaging (ie. specially boxed pairs). We still screen, test, and match nearly all Psvane tubes ourselves in-house to our own high standards. This also allows us to offer them in different configurations such as matched trios or octets.

Extended Guarantee

We offer a full 1 year guarantee from the date of receipt which covers the basics like functionality as well as noise.
