JJ-Electronic Valve ecc83s Is great for blues/rock players, good fat base. This tube clips slightly earlier than other 12ax7's giving you that edge. Tested for shorts, balanced triods, audio test so you get the best of the best.
We offer three price options:
1) Factory tested from the JJ factory - We do not screen these.
2) Premium tested for microphonics, shorts, leaks, triod balance and audio quality
3) Tested for V1 and Phase Splitter positions
