Fuzz Audio

Introducing the Working Class Tube Collection.

We built this collection for the people who actually use their gear.

The players retubing an old amp. The hi-fi listeners bringing a receiver back to life. The people who want to hear what tubes amps are all about, and do not want their only option to be modern production.

These are real vintage USA and Japanese tubes — hand tested, carefully selected, and guaranteed by Fuzz Audio.

They may not always have perfect logos or famous labels, but they have what matters: warmth, history, reliability, and that musical character that made vintage tubes special in the first place.

In our opinion, this is the best deal on tubes in the market.

Now 30% OFF for a limited time.

Tested. Matched. Guaranteed.

Not many of these left.

Every year, they get a little harder to find. Not because people stopped making them. But because the ones that are still out there keep getting used, collected, or lost for good.

We recently came across a small group that somehow made it through.

Pulled from a long-held collection. Testing strong and ready for new homes.

In this collection:

8 Matsush*ta 12AX7

Sylvania 5881 matched quad

Japanese EL84 matched pair

5 GE 12AY7

Mullard CV4004 matched pair

8 Sylvania 6SL7

And more!

Most people who own a tube amp never think about the tubes inside it.

But those glass bottles are where your sound actually begins.

In many guitar amps and hi-fi systems, the small tubes (like the 12AX7 / ECC83) handle the first stages of the signal.

They amplify the tiny signal coming from your guitar or source before it ever reaches the power section.

Because of that, these tubes have a huge influence on what you hear.

Different vintage tubes were made in different factories, with different materials and construction. Those small differences affect things like:

• noise
• clarity
• gain response
• overall tonal balance

That’s why many players and listeners experiment with different 12AX7s.

A great tube can make an amp feel clearer, quieter, and more responsive without changing anything else in your system.

The amp stays the same.

But the character of the sound can shift dramatically.

It’s one of the simplest upgrades you can make to a tube amp.
