Hi guys anyone possibily have a schematic for a Yamaha M-55 a mid 80's power amp has a few minor issues which I am more than sure I can deal with but just prefer the "recipe" if I am cooking!!! 
If anyone can PM me if a pdf is possible or gonna have to do work!!
Some "Lefthander" been at it prior to it arriving here (bits missing) save time and effort to have the squiggly bits to hand
thanx in advance as I discussed with Ben Duncan KISS is always favourite!!!
