Fender Princeton JJ Valve Kits Premium Tested
Our Fender Princeton Reverb Full JJ Valve kit includes three ECC83 valves, one ECC81, one GZ34 (5AR4) and a matched pair of JJ 6V6S output valves.
If your select the medium gain option the the ECC83’s ( 12AX7’s) are the JJ ECC83MG medium gain version. The medium gain kit has gentler break up and is good for blues/jazz.
The high gain version uses the ECC83S
One ECC83 is balanced for the phase splitter and includes a test certificate.
We have tested every valve in this kit at real amp voltages and the 6V6s have a test certificate showing the match parameters.
WE also check for noise and microphonics on the ECC83 and 6V6’s. we listen to them on our custom testers.
Made by JJ Electronic in Slovakia. We are one of the UK’s larger  official JJ valve suppliers..
