Description

New Plate Current Matched Quad of Psvane Treasure KT88-Z Smoked Vacuum Tubes

This is a tube with a confusing and interesting history. These KT88-Z tubes are produced by Psvane which was copied by Shuguang. Shuguang's version of the KT88-Z eventually became more popular due to name recognition, however this is the KT88-Z that you want. It's the original design from the manufacturer that created it. 

The KT88-Z features special carbon sprayed smoked glass which helps electrons flow more smoothly and reduces noise. As a part of the treasure series, this is one of the more high-end tubes that they produce. As such, they sound extremely detailed in hifi amplifiers and also work great as a guitar tube.

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

 We offer a full one-year guarantee covering functional defects - including noise. The guarantee period begins the day you receive your order.

    Just put 4 of these in my Rogue Cronus Magnum III and WOW WOW WOW - it’s the best this amp has ever sounded! And they are very quiet, they have my ZU Dirty Weekends sounding so good. Highly recommend.

    Superb

    This is one of the best KT-88z tubes rather they be current or NOS production. This tube is what I would call the utmost in balance. It does the entire frequency well and is quiet. Let's not forget that it's a damn good-looking tube as well. I think it would serve any application well that calls for the KT-88. Bass, detail, balanced mids, and high frequencies.
