Thanks for the info, yes, I’ve cleaned the head with isopropyl and tried a few cassettes. The problem persists.
When I’ll be changing the door belt, I’ll check again all the connections and will have a look at the wires coming from the head to see if any of them is broken, I don’t remember having any connectors there, and the whole tape deck is soldered to the control board.
What brand of capacitors would you recommend to replace the original ones with? Do you think there’s a point in replacing caps in Beolab 2500 at this point (they work fine)? I ordered foam replacements from https://www.dksoundparts.com/.
