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

+2 Swampwalker.  The thing that surprises me most is how generous Ralph has been in trying to accommodate a troublesome owner.  Ralph’s emails in this thread contain enough information for anyone experienced with tube preamps to build a close cousin to the Atmasphere phono stage.  Would it be identical?  Of course not.  The types of resistors, capacities and even wire make a difference, a big difference, but Ralph has pretty much told you the circuit details.  That is more than just about any other mfr will do.  By the way, the OP apparently bought his preamp second-hand; he isn’t an original purchaser so the mfr owes him nothing!

+3 Swampwalker.  The OP seems to be throwing a tantrum, indeed, at this point.  Weird.

Sorry you have to wade through stuff like this, Ralph...

autospec can you elaborate on what required fixing on your MP-1 that cost 2k? I'm in the market for a used MP-1 and would like to know what might go wrong.

Will found what was apparently the 3rd MP-1 ever built in a shop near his house. It needed some work (being about 28 years old: someone had tampered with the power supply as well) and we installed a number of updates to insure it working properly. It was a treat to have such an early example in the shop- haven't seen one of the original Mk1s in over 20 years. 

rsf507;   Feel free to call Ralph and ask him what was done......Then you can contact me if you would like to purchase it.........I also have a pair of the matching gold m-50 amps......

IMO
this great thread will push me towards purchasing anything Ralph makes !!!!!!
bravo Ralph
