NOS vs. ANOS vs. Tests NOS (Condition*)

These designations are strictly used to describe the cosmetic condition of our tubes. All tubes we sell test identically, come with 100% life and are guaranteed to work in your device!

If you are picky about owning an original box or wanting a specific logo, please reach out to us before purchasing.

  • NOS (New Old Stock) Tubes - are 100% brand new vintage tubes in mint cosmetic condition with show zero signs of use. You should expect a legible logo and clean straight pins. An original box is likely but not guaranteed.
  • ANOS Tubes - otherwise known as “almost new old stock” tubes are basically new, but may show slight signs of use in cosmetic condition, such as a missing logo or slightly bent pins. An original box is possible but unlikely.
  • Tests NOS Tubes - are used but still operating to specification with 100% life. These tubes are equal in function to NOS valves, yet they cost considerably less because they have cosmetic blemishes. If you plan to disappear your tubes into the back of an amplifier or do not care what the tubes look like, then this is a cost effective choice. Blemishes and cosmetic imperfections do not affect tone…

Logos: Vintage tubes have a wide variety of logos printed on them. It is not uncommon to see a Mullard made tube with an RCA or GE logo, or a GE made tube with a Mullard logo. Your tube may come with a logo such as Heath Kit, Baldwin, Fisher, Hammond, Magnavox, Fender, Gibson, Silvertone, etc. but the true manufacturer of that tube will be correct to your order. If you are looking for a specific logo, please reach out before purchase.

Our Standards:

  • All tubes are tested for microphonics and are guaranteed to work in sensitive audio applications.
  • All tubes sold are guaranteed to have strong (to spec) NOS test scores with 100% life.
  • All tubes are tested on a calibrated Hickok 539C, Maxi-Matcher, E-Tracer or other industry standard tube analyzers.
  • Tubes are guaranteed for one year and any tube can be returned within 30 days.
  • Preamp tubes are matched by gain and mutual conductance (Gm).
  • Power tubes are matched by mA and Gm.

Do not buy power or preamp tubes that have been tested solely on an emissions tester or “tube checker” - this is an inadequate test.

If you have any questions, please do not hesitate to reach out. We would love to hear from you!

At Fuzz Audio, all vintage/NOS vacuum tubes purchased through our website are guaranteed for one year from purchase date. We accept returns for tubes going noisy, losing output/performance prematurely, and of course losing function all together.  (Read about power tubes below). 

We will not cover damage from red plating neglect, glass breakage of any kind, loose bases, or other obvious faults that are due to neglect, rough handling or egregious constant use. 

This policy is meant to protect the buyer from having a tube go out on them prematurely from a flaw we missed. Tubes, especially preamp tubes, should last half a lifetime, and well beyond a year, so we want to guarantee each customer that you get a tube that will last.

For power tubes, although we will honor any faults mentioned above, we will not accept a return for a power tube that has obviously been used for 6+ hours a day for every day of the year for one year. Power tubes that have clearly been used beyond their normal wear point will not be accepted. 

If you suspect one of your vintage Fuzz Audio tubes has gone bad within one year of purchasing, simply reach out via our chat or at Support@fuzzaudio.com and we will assist you in the warranty exchange process. No receipt is needed.

Please note, it is possible we will be out of stock of the tube that is in need of a swap. If this is the case, we will either offer a refund, credit, different tube, or send the first available tube of that type when it comes back in stock.
