My new Aleph ONO Phono Section
I had to pratice my pcb skill and decided to build an ONO phono preamp following the fantastic help I had from Ed Robinson. Ed sent me all his pcb and schematics and also in unvalueable building notes and great parts list. It was so easy to build from them that I went away and order the parts. :cool:

See this thread for Ted impressive ONO: :cool: :eek:

I already built the two Unreg 40V supply PCB and the two Regulated 30V supply PCB. I made some minor change to Ed PCB by increasing cooper area. See my next post :devily:

Thanks to Ed for all his work that he was kind enough to share with me. Thanks to Mr. Pass for sharing his great desings.

I really did a great job. Take a look at this zoom of the main PCB. The trace resolution is perfect, almost like a commercial PCB. Look at the the mounting screw hole. We can see clearly the very small line.
