Single-channel preamp circuit schematic revised 8-21-84, drawn at 3x scale (2.375 inches). Shows complete signal path from pickup input through tone and volume controls to output jack. Designed for stereo applications with tone control, used only on 12-string pre amps. Includes 8 test points (TP1-TP8) for diagnostics. Second page contains stereo jack wiring diagram by K. Keller (8/11/97) for Ovation preamp models 102000/103600 with Ovation Instruments/Kaman Music/Hamer corporate information.
