This circuit from a 1966 General Electric manual makes use of an SCS. The time is given by the emitter capacitors of the unijunction transistor.
The output current of this power supply depends on the power transistor and the transformer and...
Found in a 90s Electronic Design, this suggestion to have a higher voltage in a fixed regulator...
We found this circuit in the old Mullard transistor reference manual from 1960. The circuit is...
