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
Good Low Cost Amp!
Too bad these are NOS tubes w/o an equivalent. The triode/Pentode in one tube combination makes for a good low cost push-pull amplifier. They don't consume as much space as others due to the fact the tubes shares the pre-amp with the power amp. I have a unit that delivers about 8W per channel in push-pull mode and have no problems with sound quality.

I have a Clairtone chassis that used 6gw8. Prices for those were unaffordable. I chose 11bm8 as a good priced alternative. Put a voltage doubler in the filament line and regulated it down to 10.7 volts, rewired the tube sockets, changed some component values, upgraded the puny Clairtone o/p tranny's and boy what a great sound!
