New Psvane UK-KT88 Black Plate Vacuum Tube

New Plate Current Tested Psvane UK-KT88 Black Plate Vacuum Tube

A new beam power tetrode KT88 by Psvane featuring vintage-styled black plates modeling the classic British tones of the originals before it. It's hard to go wrong with a tube designed to rival the original KT88.

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 of the models that we carry in-house. We test and/or match by Gm, Ip (plate current) and/or gain with a maximum range of +/- 15% on modern Maxi-Matcher testers. While 15% is our maximum, we strive for 5% when possible.

Extended Psvane Guarantee

Tested and/or matched by emissions on a fully calibrated Hickok TV-7 tube tester. Our goal is to match within 5% with an upper limit of 15% (15% is the industry limit to consider a set).
