This crowbar protection circuit for non-regulators blows the fuse when the load voltage exceeds a certain value. The configuration with component values can be seen in the previous circuit.
I got this circuit from an English magazine from 1977. It can still be easily assembled, as the...
The transistors of this circuit can be BC548 for NPN and BD136 for PNP with load up to 500 mA. The...
This 3-transistor amplifier stage was found in documentation from 1963. The transistors are made...
