This power supply was found in documentation from the 90s. Two power transistors are used to increase the current capacity. They must be equipped with a heat sink.
This circuit is basically the same configuration as the previous one with a power stage with...
Found in a 1969 documentation, this circuit for the 20 MHz band does not use a transformer. The circuit is...
This circuit can provide a voltage of up to 900 V depending on the input voltage. The diodes must...
