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

I am surprised you can't deduce the circuit from the info Ralph gave you. If you buy the amp and open it up, you should be able to draw the circuit from following the pathways. I used to do that all the time with old tube amps like Croft, Leak, Radford, TVA etc.

Yeah, Ralph, you are being too nice. The OP represented himself poorly. #greatthread

@trelja  Agreed. Will's work looks great and he deserves respect for his contribution to the audioplile community. Sometimes what folks mean fails to come across in text. Peace out.
