The choice of vacuum tubes in a tube circuit can make all the difference sonically. We have long experience in “tube rolling”, and access to the finest sounding new and new-old-stock (“NOS”) tubes available. On this website we list only the most popular, mostly new production, vacuum tubes. Please let us know about your actual tube components for a consultation on these listings or NOS tubes.
The Valve Art 350B tube is in very short supply at the present time, so single tube ONLY is being offered.
