Hello,

first posting on this site, nice community!
I bought a heavy neglected music reference rm-4 preamp with an external
powersupply. The former owner has been chaning a lot inside the amp,
not all for the good of it (messed up the phono section).

Does anybody have a schematic of this amp? I have a friend who builds tube amps and is willing to help me out, but it would be a lot easier with a layout,
etc. I live in europe, which means the former owner made a power supply suited for 220 volts,

hope someone can help me out,

kind regards

stefan
