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.
