Again many thanks to you, Bruce for sharing your great design and helping other DIYers here. It is not an easy thing to do and it's such a class act.

Hi, It is good to hear from happy builders. The amps are surprisingly easy to drive and sound a lot more powerful than you would expect.

Good listening
Bruce

Even with high end amplifers there is a puffff coming from speakers even when not playing anything. I don't know if they do it deliberately. Because it provides somewhat warmer presentation.

Not easy to get amps zero noise espcially without the lots of feedback or without expensive voltage regulation.
Not easy to get a mains grounded pre amp and mains grounded amp to have absolute zero ground current noise.

What happens when an opt is saturated? What do you hear from speakers? A squeal or some microphonic noise?
