Default Help Wiring Toriodal Primaries

Click the image to open in full size.
http://www.partsexpress.com/pe/showd...number=122-640
OK i'm stuck what is the correct wiring for the Primaries? I'm on 110v

BLU + VIO


GRY + BRN

// so basically i'm connecting the ends to each other. Is this correct?



Also i need someone to verify these voltages on the Secondaries
Because it is 25v+25v won't i get a voltage above 50v?

I don't know why nobody else answered your Questions:

for Primary at 120 volts you tie the dotted together.Blue and Violet
and the brown and grey together

For the secondaries your 50 volts is realy +25 to 0(zero) and 0(Zero) to -25

It might be helpful for you if you consider the dots to indicate the positive of a dry cell or battery. so on primariy you want them in parallel and on secondaries you want them essentially in series and think of the zero points to be the neutral for the chips, and on Brian's board they will become the power ground on the amp PCB

The Red and Orange become the ground.
