The Tung Sol Valve Kit 4x 12AX7 2x EL34B is our best sounding valve kit for your 50 watt amp. It offers a rich tone perfect for rock of any style. Preferred by professional musicians who value durability, reliability, and superb tone. Sound superb in amps such as Marshall and Laney.
These valves are hand-tested and matched on our AVO and custom-built testers to ensure maximum quality. This comes in addition to factory pre-matching of the EL34Bs. Matched for anode current and Gm at real amp operating voltages. Audio tested by us too.
Tung Sol manufactures their valves in Russia to the highest standards under the US Dept. of Defense Military Standard 213 Revision D. (Yes, the USA military still uses valves and keeps their test specifications up to date!)

A Note for Marshall JCM2000 Owners
The Marshall JCM2000 is a modern classic, and many are still working hard on stages and in studios. But as these legendary amps age, the original PCB boards can develop increased noise and stability issues, particularly around bias.
Using modern design tools and manufacturing methods, we’ve developed a drop-in replacement PCB for JCM2000 amplifiers that preserves the original circuit and tone, while improving long-term stability and noise performance.
If you're rocking one of these tone machines, this is the upgrade for you.
