this is my guess but need some expert input

• violet+grey on the primary
• black+yellow the secondary (My V+/V- supply uses center-tap for ground)

Thanks

Three questions need to be addressed.
1. What is your input voltage?
2. What is the output of the transformer?
3. What voltage do you want on the output?

Primary:
pair Brown/Grey and violet/blue, gives 115v across both pairs
pair Violet/Grey, gives 230v across brown and blue

Secondary:
Black & Red and Yellow & Orange each give 150VA (@ Vsec)
pair Red/Yellow and Black/Orange gives 300VA (@ Vsec)
pair Black/Yellow gives 2x Vsec @150VA across Red and Orange (Edit: yes, could use black yellow as a ground and Vsec would be 1x, not 2x)

I'd wait for confirmation from another poster before trusting me though

We still don't know the output Voltage of the secondary, so what I can tell you is that connecting red-yellow and black-orange (in parallel) will give the voltage of one coil with higher current, and connecting black-yellow (in series) will double the voltage of one coil at the lower current, and give you the center tap from the black-yellow wires.

The product info for the tranny should have both voltages/currents listed in the product description.
