Eurotubes Inc.


Since 1998 Eurotubes has been the premier source for JJ Electronic Tubes, Caps, Amps, Bias Probes, Damper Rings and Speaker Cables. We have worked closely with the JJ factory who at our request built many of the JJ tubes now available including the KT77, EL844, 6V6 and KT66 power tubes along with the 5751 and 12AY7 preamp tubes to name a few.

Our in-house testing is second to none. Using custom made matching equipment our power tubes are burned in and matched to extreme tolerances. Our matching and grading is so precise, if you break a tube we can send a replacement that is a perfect match!

Our preamp tubes are all tested using Amplitrex machines. Unlike other suppliers who charge $4.00 to $5.00 for a “Low noise” tube, all of our preamp tubes including our “Standard” tubes are thoroughly screened and selected for low noise and low microphonics.

In 2003 Eurotubes was the first to bring “Retube™ Kits” to the industry. We predicted many companies would follow and they did, offering “tube sets”, “tube compliments” and “tube upgrades” to name a few.

So what’s the difference? Here at Eurotubes we are all players and every “Retube™ Kit” we offer has been developed using the amp it was designed for to prove out the kit. All of our products such as Bias Probes, Damper Rings and Speaker Cables were designed and built because we wanted products that transcended the norm.

And finally, we stand behind all of our products and tubes offering email and phone support going far beyond any competitor. We are intimately familiar with just about every amp ever made. We can tell you if certain tubes are compatible with your amp, we can answer ALL questions about bias. We’re here for you!
