I thought all tube amps were un-reliable & noisy?
Not the case with Tube Technology. After all Man went to the moon using tubes, tubes are used in guidance systems by the military (Russian Mig Fighter jets). The most unreliable and noisy item in older style tube amplifiers were the rectifier tubes, as they are doing a lot of work charging the power supply capacitors. Tube Technology does not feature rectifier tubes in its designs, we use solid state circuitry, which is reliable and low noise.
