About Our Vacuum Tubes
We have over 100,000 vacuum tubes for sale, and our inventory is growing daily.
Our vacuum tubes come primarily from estate sales and closed TV and Radio repair shops.
Most of the tubes have been in storage for decades, most for fourty to eighty years.
Because of this, many of the boxes that the tubes were originally shipped in have long
since deteriorated or are well worn and/or damaged from the many decades of storage and handling.
A few have some water damage from leaky storage facilities.
While the boxes of some of the tubes may no longer look new, relabled, or may be missing entirely,
the tubes themselves are perfectly fine.
We catagorize our tubes under six general classes as follows:
- Dud: These tubes are no longer functional.
They are sold for display purposes.
- Low Grade: These tubes have either weak emissions/gain, missing parts
(such as a cap), or have inter-element leakage.
The tubes are still functional other than the indicated problem.
These tubes can be a low cost alternative if you don't need a perfect tube.
- Used: These tubes have been pulled from equipment. They may have some cosmetic defects,
but they are still functional and in operational condition.
For tubes that have been out of production for many decades Used may be the only choice available.
- NOS: These tubes are new old stock.
Because they have been in storage for many years, they may have been
put in other boxes because the original box wore out or was damaged,
or there may not be any box at all. An NOS tube still functions like new.
NOS is best if you need a like new functional tube but don't care about the box.
- NIB: These tubes are unused and still in their original box.
The boxes may show some storage wear or minor damage.
- Unknown: In a few cases we may not be able to test a tube or make a determination on the history of a tube.
In those few cases, we provide what information we have on the tube.
We guarentee all our Used, NOS and NIB tubes. If the tube does not function as described,
return it for a refund or replacement. Always email first before returning tubes to get an RMA.
For obvious reasons, we cannot guarentee our Dud or Low Grade tubes.
The Unknown tubes are treated on a case by case basis.
Because some tubes are rare, we may not have a replacement available. In the case of NIB or NOS tubes,
we may have a Used tube available. Always contact us first for availability.
Due to the highly volatile nature of the tube business, all Prices are subject to change without notice.
