This General Electric circuit produces pulses of light only when light stops shining on the sensor. Equivalent SCRs can be used and the trigger adjustment is done in a trimpot. The maximum load is 40W.
This circuit was found in a documentation from the 50's. The transistor is made of germanium and...
Here we show a configuration in which we have a control voltage applied from a voltage divider, which...
