Grundig Hifi Zauberklang 3025

I did a lot of cleaning on that, it was quite dirty. The usual changing of capacitors was of course necessary. The problem here still is a coupling mechanism, that doesn't work properly. I have to figure a way out to make it work again.
This radio works with ECC85, ECH81, EF89, EABC80, EL84, EM34 and has a selenium rectifier.

I googled the relevant datasheets and linked them here, because I don't own them.
