Below you can find some of the questions which we are commonly asked by our customers. Please read through these questions and see if they can help resolve your issue. If they do not, you can contact us through email at email@example.com
If the getter flash has a milky white color, then it means air has leaked in and the tube is bad. Other discolorations are usually just due to differing speeds and temperatures at which the flashing was done and do not mean the tube is bad.
A blue glow on the surface of the glass, mica, or metal is fine. A blue or violet cloud within the tube structure is bad.
An orange glow from the filament or cathode in the middle of the tube is normal and can vary from very bright to very dim depending on how it is covered from view by the surrounding structures. A red or orange glow on the surface of the plate is bad and is referred to as “red-plating.” This is caused by setting the bias of the tube too hot.
We accept Visa, Mastercard, Discover and American Express as well as PayPal.

We do not match dual triodes or other such preamp tubes, nor do we test for microphonics. We can match power tubes. If requested, there is a per-tube fee for matching.

We are constantly searching for new-old-stock vacuum tubes, and they come from a variety of surplus sources. One of our sources is our customers. If you have vacuum tubes that you would like to sell us, please request a bid list from our contact page
For an additional $1.00 per vacuum tube, you can order specific brands of tubes. Please list any brand preferences in the comments section of your order. If we cannot fulfill this request, we will let you know
Generally our new-old-stock tubes were made by the major U.S. manufacturers, along with a small number of European manufacturers. If we have a large stock of a particular tube from a single manufacturer, we will designate the tube with its own part number. If you require a specific brand, we charge a fee of $1.00 per tube for selection.
We are not Korg. We do stock some Korg parts and we handle special order items for them.
