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. 

Testing and/or Matching

Tested and/or matched at full operating voltage with regulated power supply on a MaxiPreamp tester for both gain (Mu) 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 Guarantee

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