Factory selected tubes with gold pins. The JJ / Tesla ECC82 replaces 12AU7 types.

The JJ / Tesla ECC82 replaces 12AU7 types.

Selected tubes for low noise and low microphonics. The ECC823 is a special tube to reduce gain. It replaces ECC83 / 12AX7 / 7025. The ECC823 consists of a triode ECC83 (pin 1-3) and a triode ECC82 (pin 6-8).The ECC82 side has significantly less gain than the ECC83 side. The ECC823 is therefore used to bring amplifiers with excessive gain down to a normal level. Many manufacturers (e.g. Fender, Marshall etc.) use the triode pin #6-8 as the input side, so that the ECC823 reduces the gain here.

The JJ EL34-2 is an optimized version for pure classic sound, balanced tone. It features stapeled plates, not soldered ones, similar to the construction of the old RFT tubes. This tube is an excellent allround performer.

This is the very latest edition of JJ / Tesla's EL34.
The sound is well balanced with tight bass response and great mids.

Nice mids, sparkling highs and solid bottom end characterize this tube

The JJ EL 844 has nice mids, sparkling highs and solid bottom end characterize this tube. Reduced output and earlier breakup compared to a JJ EL84 tube. You will have less clean headroom but more tube distortion setting in at lower volume compared to a EL84 tube. Drop-in replacement for most cathode and fixed biased EL84 amps.

Double anode rectifying tube. High quality, long life production by JJ Electronic.

Another awesome release by JJ Tesla, totally living up to the hype. JJ created a perfectly musically transparent KT66.

The great KT77 is back, reissued by JJ Tesla.

The bass is unique in that it compresses the very bottom end. This provides incredible bass response without ever losing control. Overall a great tube for orchestral, opera, and jazz music.
