ATMA SPHERE SCHEMATIC for a UV-1 M/M.......

I read through the whole thread again.

I understand where autospec is coming from. He is apparently quite technically adept with tube amps and wanted a schematic to do some work himself. Unfortunately there is none. So Ralph tried to provide the info needed which was very considerate. I can understand why a technical guy wants a blueprint in writing in order to do things right. Its a best practice in engineering in general when the goal is to share technical information with others. However a vendor is under no obligation to have or provide that to others. Were they authorized to do service on the product then definitely but that is not the case here.

That does not mean autospec has to live with that situation. Since it matters to him, sellng the gear is a perfectly good outcome given the circumstance. If a product does not have the feature you need then that is that.

So no bad guys in this story I’d say. It is what it is. I did get the impression autospec may have felt ganged up on but I don’t think that was the intention of most. Atmasphere has earned a lot of respect here over the years and you can’t buy that.

timlub,

Well, I suppose he will endeavor to make the change with info Atmasphere can provide, send it to Ralph to do, or sell and take a different path. His choice. He wants a phono and the pre-amp does not have one. I agree Ralph is doing what he can to address the issue and try to make a customer happy which is the most important thing.

Ironically, as I write this, I am similarly working with a customer to help him get a piece of software I provided to do some things he now wants that it was not originally designed to do out of the box. Irony!

FWIW, seems the original question and the problem at hand is being addressed as best possible by the best person to address it. I’d take the issue private at this point if it were me. Sounds like a happy ending for all should be somewhere not too far down the road one way or another.

just so I understand you have the Atmas pre-amp without a phono section? How is that? That model is supposed to have the phono section based on teh docs online.   Is teh phono section you want to install from Atmasphere or somewhere else?

Is the goal to be able to add phono as a source? Rather than operate on the device yourself, see if Atmasphere can do it for you. Or maybe just add an external phono pre-amp?

Would either of those work for you?

In general, though some may be equipped to do so in some cases,  I think it’s not reasonable to expect a vendor to provide info needed to make mods to a device. There is no way for the vendor to assure good results cost effectively.
