I'm a beginner at attempting this type of project. I've recently acquired an RCA BA-103A preamp. I have the pinout instructions. I know the preamp requires +/-15V DC. However I don't know what current rating it needs. Does anybody know this? Also, am I better off finding a power supply that offers 15V and just using that, rather then attempting to build one at this point? Of if anybody knows where else I'd be able to post this question for help.
