I know in tubes, the issue of balance and hum is always more present and dealt with in interesting ways. Also I tihnk about ZV7 and his comment about how many transformers are not truly balanced on their secondaries and in that particular amp, he talked about trimming it. I guess it is reasonable to believe that the nicer the transformer, the more testing they do and perhaps, this is a request of Nelson to them when making them. I am eagerly waiting to hear the Primrose transformers, as they are suppose to be higher quality. I would hope, winding balance is part of that improvement. Still guessing though.

in transformers - things are simple

bigger core , tight winding , double varnishing , harder baking

You should note that in The Master's board layout 6moons audio reviews: FirstWatt F6 the Jensen transformers are as far away from the power toroid as possible. He also rotates the toroid to adjust adjust the hum levels.

Thanks Ihquam, all done....

Any idea what higher mains harmonics 100Hz, 200Hz do to the sound? Supposed the mains fundamental is 50Hz.

Just found this....

"Units fitted with Plitron toroidal transformers have deeper, more powerful bass, sound more musical, more dynamic, more everything that music needs to be exciting and natural-sounding. "
Plitron's Incredible Transformers for Counterpoint

When only the half is true, I would be happy!

Anybody want to go in a some to try and match. Looking at them, I wonder how linear they are at our operating range.
