This circuit was found in an old GE manual. It uses a thermocouple as a sensor. The SCR must be in accordance with the power of the controlled load.
The proposed circuit generates signals in the range between 9 kHz and more than 44 kHz, which, it is...
This circuit uses currently uncommon components, including the 10.7 MHz (FI) filter. This circuit was...
This small power supply for low currents (5mA) is suitable for power low-power TTL experimental circuits....
