[quote author="Samuel Groner"]Re-reading this thread I realised that you're regulating 2x 24 VAC to 2x 12 VDC, right?[/quote]
Yes.
I really suck at theory in DIY. I found some formula but don't know how to meassure the current
from the secondaries. I also tried a few resistors in front of my ammeter and there were no changes
on the toroid secondaries. What am I missing here?
Well isn't this what I am already doing? I connected + wire to +12V and - wire to -12 output of my PSU to get 24V.
Yes.
So then use a pair of series resistors for the transformer secondaries to get things down to about 18 VDC at the input.

Alternatively you could set the regulators to +/-24 V and not use the negative supply. Makes about half the heat.
