Normally when i do a PSU, i have a low voltage trafo, say 18V 0 18V and with a doubler or tripler i get up to 50 something volts for my +48V psu. Now i have it the other way around, i have a big trafo and i need to lower for my 24V psu.
So rather than just injecting all of that voltage to the 24V psu and "dump" it into heat by the Voltage regulator dropping it down to 24V, and by that also risking that it excedes the max 40V input to output differential of the LM317. The solution im thinking is using a standard bridge rectifier on the 48V psu, and only 2 diodes in series with the transformers legs that feed the 24V PSU, thus having a full wave rectifier but with half the voltage or so....
Is a very simple circuit, however eventhough it makes sense to me, and ive done it "on paper" several times, for some reason im unsure on how "audio worthy" or clean will that PSU be, as opposed to using a bridge rectifier.
