    The damping comes from a small...

    F = flink: fast-blow
    T = träge: slow-blow

    Yes, that blue thing is the transformer. Probably power comes in through that little board with the corner cut off and a pair of capacitors and inductors on it. That's a line filter. Then the line...

    Agree with Ross, check the power supply. In my limited experience the 3-pin regulators tend to die.

    On the VRZ models the striped yellow/white wire is unregulated 18VDC which feeds to a 3-pin...

    That's too bad: 24 x 5mm TR seems to be a standard size. In English they are called "Acme" but that has a different thread form than the European standard, which is called "TR" or "Trapezförmig".
