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 pahse 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.
Made by JJ Electronic in Slovakia. We are one of the UK’s larger official JJ valve suppliers..
