"The box got badly crushed by USPS, which is rare.
Your insanely excellent packing left the tubes in perfect shape." - Dr. Mel R.


Each vacuum tube's electrical properties are analyzed using an Amplitrex AT-1000 which measures heater-to-cathode leakage, shorts, gas, microphonics, emission (plate current), and transconductance. Results are put on a label which is placed on either the original box or a generic white box.

What's In Stock?

STARTING JANUARY 2010, we have decided to remove the cart function and simply request you email after browsing our inventory list, or email about tube testing or bogey tubes.

All tubes test NOS in white boxes, unless noted STRONG and/or OB (original box).

Please sign the guestbook for a tube if you have used it or feel our description needs to be updated or elaborated upon! We'll also be adding scanned tube data sheets as well as any audio-related ephemera we find lying around to the Parameters & Ephemera section.

warm regards,
