Yes, excellent work...
The measured temp on the toroid hold down screw and washer keeps me thinking... will overspec the transformer to 400mA most likely...
51C is a lot and you have yet to case it up.
The screw itself is considerably cooler, but, the overall heat is more than I expected. That being said, if you look at the specs, there should be plenty of available current at 30V. Something like 400ma per secondary. However, the full heat dissipation of 25W is occurring at that load.
I am no transformer expert, but, I think something closer to the required voltage would probably be far more efficient. Hopefully we will find out soon and the custom sumr will show up to the party.
