The JJ Electronic EL34 II is a different construction of the classic EL34 tube that offers a different tonal palette than the original. This tube has a more compact plate structure than standard EL34’s. The JJ EL34 II has an increased low to low-mid end with plenty of headroom to spare. This tube has a thick and tight bass response. The mids are balanced and harmonically rich with pleasantly smooth highs. The JJ EL34 II is stronger than the original but not harsh sounding in any way. When overdriven, this tube has a warm and dynamic distortion that rivals many vintage tubes.

Garbage. Tried them in my Carr hand-wired amp. Even when played clean, the EQ is notched. When overdriven, they sound even worse, more notched and nasal. There are so many better choices out there.

Precisely matched tube set is a breeze to bias!

Recently retubed a Marshall 100 watt plexi. The old Svetlana EL34s were replaced w JJEL34ii power tubes. Balanced and biased a bit hotter than factory....the results are excellent, rich tone with deep tight bothom end and much smoother mids and highs. I am quite pleased
