TDA2009 amp power supply; Help!
Okay, so basically, I'm creating a TDA 2009 2x10w amplifier and I was wondering if having +12v 1.5a and -12v 1.5a was any different from having +12v 1.5a (was 15 but is going through a regulator) and -15v 1.5a. I was going to use a bridge rectifier to get dc from a transformer, and then even it out with some capacitors, but would a 12v transformer no regulator be best or would a 15v transformer with a +12v regulator be best even though there are -15 volts instead of -12? Or does anyone know of a -12v regulator that can handle more than 2 amps? Please help!
