Step Up Transformer sort out project.
These were very nice 1:100 transformers put in a turned barrel style case, all done by someone else..
Problem was the transformers were not shielded. There was an attempt at shielding but the face plate was wooden.
They hummed big time.

I totally encapsulated the transformer assembly in MUmetal. I turned a copper faceplate that I MUmetal lined.
I mounted the transformer sandwich construction to the faceplate using brass threaded spacers. Transposed the phono sockets and wiring.
Then I MUmetal covered the wiring area.
Tested on my system.
No hum
