New Matched Quad (4) Psvane 5U4G Vacuum Tubes

New Matched Quad of Psvane 5U4G Vacuum Tubes

A directly heated full-wave shouldered 5U4G by Psvane. This is the best sounding and most reliable 5U4G available. Don't starve your amplifier of power - this rectifier delivers stable performance. Replaces the 5Z3P, 274B and others. Electrically these will replace a 5U4GB but they are larger and may not fit in some amplifiers. 

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.
