Started this week on the Graetz beast.

[boater sam]

The can is already stripped out, I don't think it would have reformed as the top has a hole in it from new with a bit of clear tape over it which has vented electrolyte at some time.
Agreed rotating ferrites are fairly common on continental sets but the intricate mechanism of this one is a joy to behold.
Graetz were an East German company of course until quite late, I am assuming that this set was made in the later West German factory.
