This JJ electronic valve kit contains two ECC83S ( 12AX7) and four EL34 II’s.
Note that our JJ EL34 kits use the much improved JJ EL34II because it has vastly richer mid tones than the cheaper JJ EL34. The standard JJ EL34 has a reputation for sounding thin and JJ made the EL34 II to address this tone issue.
We use our SUPERMATCHprocess to match one of the the ECC83S’s and the EL34’IIs. We supply a test certificate showing the matching test results.
You should put the hand matched ECC83S in the phase splitter position next to the EL34 II’s
You will receive a test certificate showing the matching info. Valves are made in Slovakia by JJ Electronic
