JJ Electronics  ECC823 12AX7/12AU7

The ECC823 JJ Electronic twin triode is a 12AX7/12AU7 Hybrid

The JJ 12AX7 ECC823 has been developed by JJ to try and help customers tame some of the gain in their amps. The first half of the triode is a 12AX7 and the second half is a 12AU7 allowing you to tame some of the gain coming through the amp. This tube is simply the reverse of the 12DW7 which is a 12AU7 in the first half and a 12AX7 in the second half.

Typical of the JJ 12ax7 range, It has a rich and full tone with creamy distortion that does well in any 12AX7 application.

This tube can be used in any 12AX7 application although think about what you are trying to achieve as there is a large range of tubes to meet most requirements. This tube would ideally be used in V1.

I would love to take credit for finding this tube but it was a customer called it to my attention and after I researched the tube, I felt I had to try it.. The result: A great tube that does exactly what it says. I really enjoyed putting in into my amps and tube rolling against a few others.

JJ Tubes are known for known for their high quality, durability, and their excellence in tone.

JJ ecc 823 Hybrid

I own a jvm 50 watt Marshall head and always had an issue with gain saturation on the overdrive channel. The JJ hybrid certainly tames it to my liking. Very clever inexpensive and non invasive solution that does do as described. Recommended
