  • Component and Wiring Question for Yamaha S2115H Monitor

    I was recently given a Yamaha S2115H Floor Monitor.  I have found that one of the components on the PC Board is broken.  I believe that it is a power resistor that is part of the crossover but confess that electonics are not my strongest subject.  The power lead on one end of the resistor is broken even with the block so I cannot resolder.  I have looked for a wiring schematic but they do not appear to be available.  I have attached a picture, for reference it is the smaller of the two white blocks in the lower left.  Looking for someone to help identify the component with respect to the resistence and voltage so I can get a replacement.  It is marked as

    10W  20?K

    MICRON  86

     

    Thanks for any help

    Picture is too small for me to see any details, but 10W 20?K should be a 20 ohm, 10 watt power resistor. I'm not sure what the K means in this context, but a 20K ohm resistor makes no sense in a crossover, while 20 ohms does.

      Yeah, the 20 ohm k was tripping me up as well. Is there anything special about these as I have seen 20 ohm resistors that are a lot smaller. Also is there a way to get a bigger picture up on the board? Thanks again.
