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

It seems to me that:

1)Ralph has provided as much information as he can, within the bounds of practicality and reasonableness.
2)What he has provided is a lot more than what most manufacturers would have provided.
3)What he has provided is all of the information needed to readily create a schematic.
4)It seems extremely unlikely that anyone else has created a schematic.
5)A lot of the information you indicated is necessary beyond what Ralph has provided, e.g., "parts placement for low noise problems," would not be included in a schematic anyway. (The Sams "schematics" from days of yore, that were referred to earlier, were a good deal more than just schematics).

Those are the facts which must be dealt with, as I understand them. Why those facts should result in a reaction such as "I think I’ll get rid of all of the Atma Sphere stuff I have" is beyond me.

Ralph has been very reasonable and cooperative. 
Very bizarre attitude from the OP.

I just paid Atma Sphere 2000.00 to repair a MP-1 .....I'm not asking for anything but a schematic.....It's not like I'm a bad customer.....My entire Atma Spheresystem is for sale.....It will be listed on Audiogon..........The best way to fix the problem is get rid of it.....Then I don't need a schematic or any service.......Problem solved.......Will

Very understandable. Not all manufacturers will go to the trouble and cost of producing user engineering schematics and maintenance manuals. In fact very few do. ATC have sent me specific circuit diagrams and board layouts (two separate pieces of info about the same circuit board) in the past. ATC don’t have a problem with this because they are an engineering driven outfit that expects and anticipates that professional users will need to sometimes make onsite repairs on damaged gear (misuse being a common occurrence in a professional facility that is leased by various producers and musicians regularly).

The cost of proper professional documentation (engineering diagrams) and revision tracking is not surprisingly very costly and it is often hard to justify in a boutique market. In a boutique market, personal notes and hand written schematics are more than sufficient for a small manufacturer to produce great quality gear. Unfortunately this is not suitable fir dissemination to repair technicians....

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.
