Hi guys,
Wanting to replace an existing transformer (to fix hum and for fun of learning), I ordered a new one, in 2x115v to make it an easy replacement but it arrived as a 230v.
I’ve read about serie or parralel wiring but didn't find anything about the 3 wires only case.
The original has 4 input and output wires:


The new one only has 3 inputs / 4 outputs:


I feel ok to wire the outputs, black/black instead of blue/blue and w/w instead of brown/brown.
But how should I wire the 3 inputs on the 4 pins input connector?
Thx!

The TS100va is 230volts only primary; Blue - blue.
Green/yellow is electrostatic screen and goes to earth.

Awesome!
Thx for the dim bulb tip, just learned about it!
So blue-blue for brown-black, and I believe there’s no polarity here right?
On the pcb it’s pretty clear where go the 2 positives, pin 2 and 4 from left to right here (better by transparency when I had light in the background).
And I could clearly see the earth going from the inlet to few points on the pcb, where the screws would touch the case.
So can I directly wire the Green/yellow to the inlet eye that is free here? (top left)
