Cool My Aleph ONO/XONO PCB

This is my project of Aleph ONO (nearly XONO because it's dual mono) PCB. Routing is almost ready. What do You think about single track ground instead of plane (working as a shield also) in this design?

This is missing the MC stage, isn't it?
Concerning your artwork: It's nice and well thought, but: you have only very few tracks on the top layer, almost a shame to go double sided for that. Should be possible make it single sided without much effort.

Yes, MC stage is missing. This will be an option (you can see additional supply pads). I was thinking about single layer boards for this one (few jumpers should be enough) but I like to have transistors placed on PCB working as a heat sink. I will consider this once again.

I took an article about XOno recently published in the magazine LP as a primer.
Thus I decided to use a hatched polygon for the design.javascript:smilie('')

Thanks
I have single layer board ready but I still think that double sided will be more useful here – transistors will be mounted directly. Few more hours on this one and I will probably order few of them.

You don't need heatsinking on an Ono. So you may mount the transistors vertically. I still vote for a single sided board.

Oh no.... Not Damian again....

I might as well get it over with since it will undoubtly come up soon. Are you planning to have some boards made as with the 1,7? I'm starting on mine next week or so.

Hallo Damian,
You have finished your Xono project? Please tell us the experience with your design. Did you make changes of the routing on the pcb? Please show the result of your work.

Congratulation, you did a great job. The Xono pcb is well thought, simple and clear like your pcb of the P1.7.

Greetings from Vienna

Helmut
