Fender Princeton JJ Valve Kits
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
We have tested every valve in this kit at real amp voltages and the 6V6s have a test certificate showing the match parameters. Fender fit “Groove Tubes” branded versions of these same tubes in their Fender Princeton 68, the modern version of the 68 Siverface.
Made by JJ Electronic in Slovakia. We are one of the UK’s larger official JJ valve suppliers..
