McIntosh was known for its output transformers which had interleaved windings and insulation between each layer of winding, this was NOT something that could be spun like a top and wound in seconds, as shown in the video. Slow hand winding is also done to prevent excessive stress on the wire in the winding process.
The printed circuit board on the back panel that is used to make the connections to the input jacks and the speaker terminals is not the way to go to make good connections; I would want connections to be wired and soldered.
