Hello all - does anyone out there have schematics for Demeter (VTMP 2) or Summitt (MPC 100) units. Contacted both companies but either they no longer have copies (Demeter) or can’t supply due to restrictions (Summitt). These are both units bought and owned by me and used (till they broke) for many years. Any help is very much appreciated - just want to be able to fix what I own. Cheers!!
