SPT - Canon AE1 Guide

This comprehensive service manual for the Canon AE-1 provides technicians and skilled users with detailed adjustment and repair procedures for this classic single-lens reflex camera. The guide covers critical calibration points including the SV-TV resistor network, maximum aperture correction, shutter speed synchronization, and meter calibration with precise reference specifications. You'll find exact measurements such as curtain travel time (11.3 ms ± 0.3 ms), flange focal distance (42.14 mm), and aperture correction pin settings needed for accurate adjustments. The manual includes complete electrical schematics and pin configuration diagrams for the camera's control circuits (PX1, PX2, PX3), along with measured voltage readings across different operational states. Systematic troubleshooting sections address frequent problems—shutter release failure, battery-related issues, and metering malfunctions—with step-by-step diagnostic procedures to isolate the cause. Component replacement guidance covers solder joint identification, part removal sequences, and proper reassembly techniques. The workshop manual also details disassembly order and reassembly protocols, essential safety notes (such as battery disconnection before unsoldering), and power consumption data (18 mA during metering, 40-45 mA at shutter actuation). A 4.7K calibration resistor is specified for meter alignment procedures. Coverage extends to closely related models: AT-1, AV-1, and A1. This repair manual is essential reference material for anyone performing service or restoration work on Canon's AE-1 platform cameras.
