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 PolicyWarranty 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.
We can not accept returns that don't have an authorization, are past 3 month, or are returned improperly.
These guidelines may be updated without notice.
Ratings & Reviews
Kicks performance up several notches
by Marc Cogan
Description is absolutely correct. The original Chinese 6J1 tubes in my Little Bear headphone amp actually degraded the performance of my headphones. Replacing them with this GE tube turned out a rich warm result, and a sense of 3D space with sparkling distinction of the various instruments across almost the complete range of music I listen to
If your using 6j1's this is the tube for you. I recently bought a small single ended headphone amp that came with 6j1's. The 5654 is a huge improvement! If you like the sound that comes from a cheap transistor radio then keep the 6j1's. But if you want a nice full well rounded sound then get the 5654's. A small tube at a small price with a big sound.
very nice sound, fast delivery, well packed
