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.

- 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.

My Review


The JAN GE 5670 / 2C51 tubes I just got are an unbelievable improvement with my Chinese components! The depth and punch is amazing, and a noticeable improvement over the stock Chinese tubes that were supplied. For the price, you cannot go wrong. Thanx, Jim



Replaced the 6N3 tubes in the Little Bear P-8 headphone amp with these. Also replaced the 6AS7-G tube with a CRC/JAN RCA tube. Interesting note, both the 5670 and 6AS7G tubes were considerable smaller in size. With a total investment of $200 I have an absolute killer amplifier. Shop smart. Shop S-Mart. The sound is detailed like sparks from mesquite chunk charcoal.

I put these into my little bear pre amp 8. Great tube. A lot shorter than original tubes. To the other person with the same amp, use tube-saver sockets to bring them up to the correct height. Good luck if you read this.

Excelente tubos para reemplazar los tubos chinos


Instalé estos tubos en un Preamp FX Audio Tube 06 6N3 y son excelentes tubos, sonido muy limpio y claro. Reemplacé unos tubos chinos que el equipo trae de fábrica, aunque tampoco sonaban muy mal, pero la realidad es que estos son de mejor calidad y audio.

Replaced stock tubes that came in my Monoprice Pure Tube Stereo Amplifier with these JAN GE 5670s.

I was initially disappointed with the sound coming from the stock amplifier. Persistent squeals and phaser sounds, and I was thinking that having a tube amp was only something "romantic", and not something that added quality to the music.

After reading that using good tubes might have an impact, I went for these.

WOW. What fun! These tubes are SILENT! And yeah, they provide a richness to the sound that I don't hear with my solid state Onkyo.

Thank You The Tube Store! Your "Shop by Amp" guide is fantastic! These are great tubes!
