We found this circuit in the 1964 RCA transistors manual. The transistors used are uncommon today, but they can be used equivalent. The circuit controls the operation of a heating element.
We obtained this circuit from an old European publication. It generates sinusoidal signals...
This circuit consists of a variation of a 4-input control, with the difference that we have only...
Photoelectric cells can be used as sensitive light sensors. However, the low voltage they generate...
