My first ones failed at less than 2 hours. Seconds at about 6 hours. Thirds at about 300 hours. Very frustrating. I am thinking of giving up on these amps and tubes as it is difficult to to deal with failure when you don't have a Shindo dealer nearby.
It maybe an amp issue. Only ten of these have been produced. It's possible that the power on parallel SET Shindo amps has yet to be be perfected. Who knows. What I do know is I have no music. Very disappointing.
