The EH-12AX7 tube has a nice balanced sound, a very low noise floor and excellent performance in terms of microphonics. The lack of microphonics may be due in part to the return of a shorter plate structure or better materials. I’ve had some samples that were tried in various amp stages. Pre-amps, tone stacks and phase inverters, a winner in every location…I have used the EH to successfully tame amps that defied all other attempts to kill microphonics and unwanted feedback.
