Hi
I'm currently designing (mostly cloning) and old audio -tool- that use a single -24V supply
Probably artefact from early Ge design, even if it's a Si transistor design.
The question is about regulation IC and design choice.
At this stage I think I should have the room on a single eurocard (100x160mm) to fit the rectifier/regulation too.
Is there any technical reason to use let say 7924 -normally wired- over a 7824 with output referenced to GND and GND pin as -24 output ?
I see the benefit of 78xx/79xx combo in a symetrical supply with centre taped main trafo, but here ?
Cheers
