Dynaco Stereo 120


I was looking through the for sale pages of a website and came across the images of the insides of a Dynaco Stereo 120

It was evident that a winding around the capacitor was done, does anyone know why?
Is it an electromagnet that has been wound, or simply to introduce inductance, is this an old lost technique?

I am curious, and figured someone in Agon might know?

I agree with @oldhvymec.  The one I built in the late 70s didn’t have the same, how should I say it, precision in its final build. Was a fun project.
