I'm planning on making an external power supply that I can use with all of my amps, one at a time, like how the X-PSU can work with all of those different Music Fidelity units. The circuit I currently plan on using is the dual supply Kevin Gilmore uses for his Class A amp for dynamic headphones, except I plan on using a LM350 with its counterpart, and limiting the current to maybe 2.5-3 Amps (since the LM350 only outputs 3A anyway).
What's the most practical way of connecting the dual supplies from the external PSU to the amp, with V+, V-, and ground connections? One amp will only use V+ and ground (Szekeres), others will use all 3 (Apheared #42, and future amps).
