If it became like that suddenly I suspect a leaky bypass cap somewhere in the set. Most of those West German sets have taps on the primary to set the line voltage, but I don't think a line surge was the culprit, a few volts would not cause that in such a short time, I suspect some part going bad on the secondary side.
