Who needs more current and / or voltage – may be interested in this rather simple circuit with IC µA723 (about 50 years old, but still available for little money = UA723 / LM723 / MC1723 / …). The voltage can be controlled between 1.2 … 35 V, current can be limited between 0.1 … 2 A) with 3 pots:
Since many years I am using this power supply – built in an earlier used metall case with meters – in my hobby corner:
with this parts:
for a version of max. 1A it might fit in an empty Lectron loudspeaker block – let’s see…
Here is the PCB ready for wiring:
