Hi,
I need some help with this stage of my build. Using Sowter 9062e input transformers, and the lead colour indicators on the PCB don't match the transformer leads. I'm also not sure whether to join the blue and violet leads of the secondary?
Here's the PCB:

And the transformer specs:

My current thoughts are to wire as follows (colours are transformer wires, ignore PCB):

PRI HI = Pink
PRI LO = Grey
SEC HI = Red
SEC LO = Yellow
CT = not sure. Join Blue and Violet and don't connect to this point? Connect both Blue and Violet to this point?
ISOLATE = White

Any help greatly appreciated.
Cheers
Stephen

That's correct, i've got it like this working.

I think now it's configured 1:4
