  2. Probably 2.2ohm 1/4 watt red 2, red 2, silver 10% gold 5%
    (tolerance) it acts like a fuse. Better check for a short after that
    or you'll be burning those as fast as you can replace them.

    I think the value is lower than that. Silver as a multiplier is x.01, so
    probably 0.22 ohms at 5% tolerance.

    Have a look at

    http://www.dc-daylight.ltd.uk/Valve...nent-Colour-Codes/Component-Colour-Codes.html

    which should confirm it. I would agree, however, that there is probably
    something else wrong, for the resistor to have failed like this. If it is an
    output transistor emitter resistor, then the transistor it is connected to,
    as well as possibly others in the vicinity, is almost certainly fried.

    ..22 ohms, 5% ?

    If you are inclined to email me
    for some reason, remove NOPSAM :)

    Maybe the R's are still good (even tho' overheated)
    If I am correct, most resistors would fail Open-Circuit.

    Perhaps a Low Value Ohmmeter will be able to give insight into the value.
