    Hi Ex-tension thanks for afford but it's an old TRB4P bass that I have.
    Do you have any other suggestions to find the elektronic circuitdiagram of the TRB4P (the old ones first serie I believe)

    Thank You

    Yes indeed a plopping sound, like a capacitor which cannot hold it's load.
    Do you have any suggestions?

    So, what's the problem?

    I don't understand why do you need other suggestions. With the Google search you have several results. Did you try to see those manuals from the search results? None of them corresponds to your bass?
    This one for example: YAMAHA TRB-5P Service Manual
    The number of strings doesn't matter, the circuit is the same. Try to download different ones and see if they correspond to your bass.
