    name Varistor
    model 14d681k
    max volt ac420v, dc560v
    Varistor 680V
    terminal volt and current (max v / a) 1120v, 50a
    capacity 290pf
    Watt 0,6 W

    the problem:
    i cant find the original.

    my question:
    is anybody know if this one, on the buttom, can replace it ?
    its not look the same at all.
    looks different size,
    is the replacement suppose to do the exact functioning as the original?

    As well as operating voltage, the maximum energy rating in Joules is needed, the physical size is one good indicator of this.

    Thanks alot Max for your fast answer,
    i want to verify that i understood your answer,

    so this replacement varistor is not a good one.
    i still must find other varistor that will fit the original one,
    is that correct ?
    any idea where i cn find one?
    didnt find in all the net, except one seller on ebay , on germany that sell stock.

    thanks again,
    itai
