New Matched Quad (4) Psvane 6SN7 Hifi Black Plates Vacuum Tubes

New Gain Matched Quad of Psvane 6SN7 Hifi Vacuum Tubes

A classically styled and handcrafted 6SN7 from Psvane for high fidelity audio amplification. This tube features vintage-style black plates and shouldered glass. These features give it a closer sound to the CV181 or 6F8G which are both prized tubes. Excellent highs, smooth mids and nice extended bass. 

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 Guarantee

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