CONTAX - Contax RTS SPT

Complete technical service manual for the Contax RTS single-lens reflex camera and mechanically compatible Yashica FR series models. This workshop guide delivers detailed adjustment procedures for the shutter mechanism's critical components—first and second curtain travel times, X-sync timing, curtain registration, and both manual and automatic shutter speed calibration across the full range. Includes full wiring schematics for all circuit boards (main amplifier board, switch amplifier board, LED board) and terminal board diagrams (lens mount, rewind side, wind side), along with technical cross-section drawings of internal assemblies and the complete shutter and mirror-box module. The troubleshooting section systematically addresses mirror release failures, LED display malfunctions, shutter operation problems, and faulty timing issues, with step-by-step diagnostic procedures including continuity checks and resistance measurements at critical test points. Complete disassembly and reassembly sequences for both the camera body and shutter/mirror assembly, reference voltage specifications for all circuit testing, and identification of replacement and revised component parts. Indispensable for service technicians and serious restorers performing detailed camera repair, maintenance, and full mechanical restoration.
