This JJ valve kit contains one ECC82 ( 12AU7) three ECC83S’s ( 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.
You will receive a hand selected matched ECC82 and the EL34 II output valves are hand matched and you will receive test certificates.
We test every valve that we sell to assure a top quality product. Valves are made by JJ Electronic in Slovakia
