Function of component in flash tube trigger circuit?
http://home.graffiti.net/diverse:graffiti.net/sf2.jpg
No markings, a black potted box 7x7x 15mm external dimensions. If a stepup transformer , why so small? 0.3 ohms between blue and red lead and 144 ohms between blue and brown lead which goes directly to the trigger filament around the flash tube. Red goes to ground and blue wire goes via 0.2uF, 250V capacitor to the SCR cathode. 22mH and 20uH inductance -- Diverse Devices, Southampton, England electronic hints and repair briefs , schematics/manuals list on http://home.graffiti.net/diverse:graffiti.net/ |
