I am slowly putting together a Zwackery. I am trying to wire the dual power amp between the sound board and the speaker. The schematics mention pins 2&3 going to the original power supply. I don't have the original supply and am working with a standard switcher. My question is, what is the voltage that this board requires and can I run it directly from the switcher?
