I am making up a power supply for an amplifier I intend to make. I thought I would use an toroidal tran. It is a 230/115, 160va, 48v on secondary to be used in a parallel form so as to get two 24v leads. It will be parallel on the primary also which will use the 115v supply. My question is where do I get the neg. for the secondary as four of the secondary wires are jumped so as to use the parallel circuit. I have used a regular tran. that was center tapped and the central wire being neg. made it easy. On the sec. of this tran. it has four wires , black, orange, red and yellow. Bk. to Or and Red to Yel. gives me the two 24v leads. Help on the neg.? Thanks, IA
