New Plate Current Matched Pair 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.

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.
