Additional Information and Downloads

What does "NOS" mean, anyway?:



Commonly known as "NOS," the term New Old Stock simply refers to tubes that were made years ago but have never been used. Much like antiques, "NOS" tubes are currently not being manufactured and this means their supply is dwindling while the price continues to rise.



For most NOS tubes we have a variety of brands available. Typically these are the common brands such as RCA, Sylvania, GE, Raytheon, etc. However, there are instances where lesser known brands are in stock. If you have a particular brand you prefer you can simply request it in the Order Comment box when you place your order.


Warranty Information and Return Policy

Warranty Period: 3 months



All our tubes are guaranteed for 3 months from the date of purchase. (Any exceptions will be noted on that tube's Warranty tab)



If you receive a tube that does not perform to the manufacturer's specifications, please do the following:



- contact us to get a return authorization

- return it via regular mail within 90 days from when we shipped it, and we will provide an exchange or refund of the full purchase price of the tube.



Returns not related to warranty or defect will be considered at our discretion, and are subject to a 15% restocking fee.

These guidelines may be updated without notice.

Winged "C" (SED) 5U4-G Black Plate Yaqin 300b

What can I say. Wow.

Winged "C" (SED) 5U4-G Black Plate in Woo Audio WA6

by

Absolutely transparent in my Woo Audio WA6 headphone amp, revealing BIG differences between various driver tubes. Haven't wanted to put my $160 Sophia Princess 274B back in. Great service from Richard, fast delivery also.

Increased air, space, and depth

by

Just plugged this in to my Decware SE34I.4 and my first impressions are coming in. There's immediately a greater sense of air and space around the music compared to the Valve Art 274b. Only gripes so far would be that it's maybe even too much air for me. If your amp lacks highs extension, this might help you but for my ears I feel this might get fatiguing and hope it will smooth out with some break in. It also sacrificed a bit of the lower mid range punch to get the highs.







That said, it's smooth and grain free. Will report back with any changes post break in.
