Even rarer was the 6072. This may sound unexpected, but really, the best place to read about tubes, is such a boring document like a data sheet, and not forum babble.

The JAN-GE 6072A tube is also a great tube to tame high-gain preamps because it can be used instead of a 12AX7 tube without any modifications to the circuit. Reverb has your back if your item is lost, damaged, or doesn't match its description.

Compared to a 12AX7, the EH 6072 has 84% of the gain and the JJ 12AY7 has 75% of the gain. It is only a 9% difference, but if you find your usual 12AY7 does not cut enough gain, then the JJ is what you want to try.

2009年9月19日 · The GE 5 Star GL-6072 is one of the finest 6072 tubes ever made. In fact, the GE 5 Star 6072 and 6072A from the 50's and 60's are the only 6072 (12AY7 variant)tubes I recommend in high-end applications. They usually do need to be screened for noise and microphonics but, if this is an issue, you will notice when you go to use the mic.
