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?

The output transistors are wired to the capacitor positive, that white wire connected to the negative terminal of that (output) capacitor, then wrapped around the capacitor in series to the speaker terminal. The cap blocks dc and the wire is an inductor which stabilizes the output if the speaker load is too capacitive.
Sure did a nice job, no lipstick on that one, very clean..
Sure not stock, ay? I've seen the winding before.
This person, took a lot of time for sure, quite an artist!!

Wonder what his point to point looks like..

Thanks, I'd never seen it done before, quite ingenious way to filter the output like that. I suppose it's a technique used for a long time? It's new to me.

@oldhvymec - not sure of the lipstick comment, but yeah when I saw it I thought it looked both aftermarket and neat. Clever stuff to be sure.
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.
