Bought an Achiever 321AZ flash recently which I hoped may suit an impecunious friends Nikon EM. Gadzooks ! Trigger voltage of 240 Volts ! I can strip,clean, and reassemble an iris diaphragm, but I need help with this : can I solder a simple resistor into the base of the hotshoe to give this dear lady a flash she can use to photograph her adopted baby ? ( yes,I know about the dangers of charged capacitors,etc.) -any input welcome.
