    Are you sure those aren't the device data codes?
    What are ALL the numbers/characters on the device?
    What kind of package is the component in (the case style)?

    unfortunately it doesnt really help too much. They are not standard device type numbers
    more likely they are manufacturer part numbers ( the amplifier manufacturer than is)

    do have a service manual for the Amp ? if not, it would be a good idea to do some google searching. Do you have a schematic of the circuit showing those parts ?
    see if you can find some service info and post a link so we all can have a look and see if we can help further :)

    W9434 and W9439 are date codes, not part numbers.
    70483180 is the part number. This part is obsolete. Here is a cross reference.

    This part is supposedly on stock here.

    I was unable to locate a full datasheet. All references I found show the cross reference table only.
