The JJ factory was born out of the ashes of the former Tesla factory. They currently make a range of High quality valves based on some of Tesla most famous designs.
The JJ 12AY7/6072A is a low gain signal valve that was used in early 50ís Fender amplifiers. This valve is normally put in the first gain position to lower the gain of a pre amp circuit. This will reduce the gain by around 50-60% so will give your amplifier more clean headroom.

This valve is also used by Harmonica plays to reduce feedback that they have problems with. This valve produces a warm rounded sound with low gain which will clean up and tame the harshest of pre amps.

We offer two options:
1) Factory tested from the JJ factory
2) Balanced -matched triode sections for Phase splitter, Audio & Tube microphones
