This circuit was found in a 1975 documentation. Current general-purpose transistors can be used, and the power is supplied with relatively high voltage. The gain is 30 dB.
This non-regulated power supply uses a single secondary winding transformer. The secondary voltage...
Using a small incandescent bulb as a regulator, this Wien bridge oscillator produces a sinusoidal...
The figure presents a configuration that can be very useful for audio equipment designers. What...
