    In the present case to avoid having to take this present so-called
    "professional" amp-head apart.
    Failure due to inadequate soldering due to heatsinking of the resistor leads
    in the first place. I will deform the protruding leads with a pair of worn
    out end snips before re-soldering properly.
    Other occassions where replacing the resistors and obviously solder was
    affected by long-term heat then abraiding back along the traces and doing
    long soldering between extended lead length and traces.
    For vibration induced problems replacing with ceramic bead insulators
    between the resistor and board rather than just flapping about in mid-air.
    Any other tips ? particularly maybe tying together somehow particularly off
    the board, on end, vibrating / flapping resistors or vibration induced
    failure corrective repair in particular

    Hi,
    Try to find a copy of Mil-spec. training manual for soldering.
