Lexicon MX200 documentation in PDF format, about 1.22 MB, indexed as a schematic for this dual reverb and effects processor. The doubled extension in the original name is harmless, and the file opens in any PDF reader. Use the diagrams to trace the audio path through the converters and DSP, check the power supply rails and locate parts around the jacks and controls. Before ordering components, confirm that the hardware revision of your unit matches the drawings, since production changes can alter part values.
