A fully tested re-valve kit for 45-50 watt amplifiers from Hiwatt, Marshall, Rooster, Selmer, etc.
Kit Includes
- 2x EL34 II matched by hand in-house on our custom output valve tester which also does audio testing and matching at real amp voltages
- 1x ECC83S (12AX7) matched and balanced for the phase splitter position
- 3x ECC83S (12AX7)
- Test certificates for the matched EL34 IIs and balanced ECC83S
We test each valve at real amp voltages on our suite of custom valve testers which also check for noise and microphonics.
Our JJ EL34 kits use the much improved JJ EL34 II. It has vastly richer mid tones than the cheaper JJ EL34. The standard JJ EL34 has a reputation for sounding thin, so JJ made the EL34 II to address this tone issue. Get the sound you deserve!
Tubes made in Slovakia by JJ Electronic.
Includes our class-leading 180 day warranty.
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.
