hi i my knowledge is limited but ive built a power supply for my amplifier projects as per attachment 1 x 500va transformer with 2 18v seondarys the voltage i need must be less tham 30v dc to drive most amp prodjects the problem is there is no center tap! if i put the secondarys in series i would get a center tap but the voltage becomes 36VAC / 50V DC AFTER RECTIFICATION ! IS THERE A CIRCUIT THAT I CAN USE TO KEEP THE 18V SECONDARYS ???? CREATE A VIRTUAL GROUND MAYBE ( DUNO IF THAT WOULD WORK ) ANY SUGESTIONS ANYBODY THANKS
