Anyone still have the schematic? (Pass Ono )The stripped down MM only version is fine. All the old links I am finding are broken....still searching. Peal 2 is fine for my MC purposes, just interested in MM so many were building several years ago.



Thanks for any working links

These boards are the first Ono I made. See my homepage at DIY Audio Projects. I gave the boards to a DIYer who asked for it. They are unique, I build them only once.

My names was deleted from the boards after PCB Design by ...

It is allways the same with a lot of guys in the world and the reason why I no longer share my knowledge.

Many thanks...a mystery solved. 🙂

I cannot understand why your name was removed...it seems so petty. I bought this from a DIY guy for very little money, it works but is a little distorted in one channel. I will take the boards out and check them and then put the PS and the amps in different boxes.


@ Russell,

Apologies for taking up so much space on your thread...😱
 
wow, that's pretty bad/sad ...

Pass Xono is a first rate phono stage , but production units are not the same as published schematic. Some components are tuned at the bottom of PCB-s.
Its designer had no will to tell the whole truth. How did they got published test voltages with BL group J-Fets as they said to use? Impossible!All the cloners use the lowest Idss J-Fets for 70db gain. People at Pass Labs were not delighted with widespread open cloning and even making profit of it.
I tried Jung super regulators, but the best results are with cheap 7815/7915 regulators with voltage dividers for 30V , as in manufactured units. In spite of 4 electrolytic in the audio signal path, low level details are outstanding.
High working voltage and active RIAA eq. give high overload margin for low level clicks and surface noise.
