Resistor Behavior Question

[timmy]

well im not a tech for these sets but if its an old resistor and the first time firing up after awhile then i would think that there is a short somewhere maybe the old paper caps. if the old resistor just had dust on it maybe it would burn away and thats it but your saying boil, or bubble, and venting smoke to me spells a short. i would double back and check all the connections on the lytics as it is easy to place a wire in the wrong place by accident being very careful not to,it happens. check and see what the value of the resistor is to be and compare the old one maybe it went high out of tolarence. hope this helps.
