JJ Tesla is a mainstay in the Vacuum Tube industry. We have been dealing with Tesla tubes since the early 90's, now called JJ. Here are the virtues of the JJ Tesla 300B Triode:

1. Exquisitely constructed, gorgeous construction
2. Fantastic and consistent high Gm measurments
3. Extremely Reliable and Robust, very conservatively designed
4. Sound fantastic. The sound compares to the NOS tubes at a fraction of the cost.
