New Plate Current Matched Pair of Psvane 5881 / 6L6GB Hifi Vacuum Tubes
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 you're 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 with regulated power supply on a MaxiMatcher tester for both plate current (Ip) and general mutual transconductance (Gm). Our goal is to match within 5% with an upper limit of 10% (15% is the industry limit to consider a set).
A note on Psvane packaging & testing
You are most likely familiar with seeing Psvane tubes sold in proprietary Psvane packaging, factory tested, and/or matched in pre-made sets. In order to provide a wider variety of sets (including singles), we hand-test and match all models that we carry in-house.
Extended Psvane Guarantee
We offer a full one-year guarantee covering functional defects - including noise. The guarantee period begins the day you receive your order.
