OLYMPUS - olympus T20 tech
by OLYMPUSThis comprehensive technical guide covers the Olympus Electronic Flash T20, a series-circuit auto flash unit designed for TTL camera systems. The manual begins with detailed main specifications including flash type, coverage angle (40° vertical and 56° horizontal), flash duration (1/40,000 to 1/1,000 seconds), and recycling characteristics. Operating modes in both AUTO and MANUAL configurations are thoroughly documented with aperture-by-distance tables for ASA 100 and ASA 25 film speeds. An illustrated nomenclature section identifies all control elements and physical components of the flash unit. A complete disassembly procedure with numbered figures guides technicians through removal of the upper housing, battery chamber, and internal assemblies. The adjustments section provides step-by-step instructions for calibrating electronic flash light output using a standard reflector and variable resistors on the circuit board. A comprehensive parts list catalogs over 100 replacement components, including part numbers for condensers, transistors, diodes, transformers, and other electronic elements. The guide concludes with exploded parts diagrams, a wiring diagram, and an AM circuit diagram, providing all necessary documentation for maintenance, repair, and restoration work on the T20 flash unit.
Documentation must be downloaded on a computer (PC, Mac, or Linux).
Do not use a smartphone or tablet to download documentation; they generally lack sufficient memory capacity to handle large files, and few users know how to locate the download folder on these devices.
