SPT - Canon AE1 Guide

This comprehensive technical guide addresses adjustment and troubleshooting procedures for the Canon AE-1 single-lens reflex camera. The document outlines critical adjustment locations including SV-TV resistor, maximum aperture correction, shutter speed settings, and metering calibration. It provides a methodical adjustment sequence with precise reference values: curtain travel time (11.3 ms ± 0.3 ms), flange-to-focal-distance measurement (42.14 mm), and maximum aperture correction pin specifications. The guide includes detailed electrical circuit diagrams and pin assignments (PX1, PX2, PX3) with measured voltages for various configurations. Troubleshooting sections address common symptoms such as shutter failure to release, battery issues, and non-functioning meter, supported by systematic diagnostic steps. The document covers component replacement procedures, critical solder points, and reassembly protocols. It includes disassembly highlights and reassembly procedures, safety precautions (battery removal before unsoldering), and a typical power consumption table (18 mA at meter, 40-45 mA at shutter release). A specialized calibration tool is referenced: 4.7K resistor for meter calibration. The guide also addresses similar models AT-1, AV-1, and A1.
