    Hi, I have this board that got damaged and I need help to identify the two broken capacitors. The little one is a 331 J5A so is this a 330pf? The other one I have no clue. The manufacturer of this machine had the boards made outside and can not supply me with part information. The missing cap is next to a chip. It is gone off the borad but I am assuming that all 7 chips would use the same cap. All of the remaining chips have the small 331 cap next to them.
    Thanks for your help, Bob

    I can't make out marking on the firsy pic with the caps. The device in the second pic is a resistor network. The individual resistors are 560 ohms, but they may be individual resistors rather than a bussed network. A meter can tell.

    I can tell too. :)

    The resistor network is marked 8X - 1 - 561
    which is 8 pin, the '1' means single ended so each resistor has 1 accessible pin.
    That means there are 7 resistors, and the other pin is the common which is marked with the square dot. And of course beenthere is right they are 560 ohm.

    For comparison a 8X-2-561 would be 8pin, have 4 resistors each having 2 pins.

    Any parts supplier with a good range will have these in stock, someone like Farnell will have it you just need the 8X-1-561 value and give them a call. :)
