Default Re: Toroidal Transformer voltage reduction by removing turns

I would guess that the on load voltage of that transformer would be much closer to 20 volts.
I would try it on load before any modification.
It is strongly recommended to de-rate transformers if running on continuous rectifier loads.
The charging pulses going into the capacitors often make transformers get quite hot.
