Re: Hurrah, a new transformer.
also put fuses in primary (2AT) and high voltage secondary (0.8-1AT after 1.st cap Ub+ to the output transformer) to protect the transformer in case of some incident or short

Re: Hurrah, a new transformer.
Congratulations!
I dont want to be a partybreaker, but lamination stack looks little bit small (thin)....
Just measure the current (primary, secondaries) and temperature after one hour in use if the curents are normal....
If the transformer is not hot, then is ok

Re: C-lator hum
They are open, as in infinite Ohms... Can't believe they are burnt. That should have shown. So somewhere in the coil there is breakages, right? Too hard handling of the wires? Did I pull them too hard? I did handle them carefully. Very strange, this is first time in my life to hear that.. ok heater...
