This circuit is from Mullard 1969 documentation. The circuit operates at a relatively high supply voltage and has a 10 Vpp output. The transistors are of the time, but admit equivalents.
This circuit is from Motorola's 1990 Linear Databook. We can implement it with other operational...
This power supply is protected from shorts in the load. The BD135 must be mounted on a heatsink...
We found this circuit in a Poptronics of the 90s. The circuit operates from 100 kHz to 30 MHz and...
