I'm not familiar with the model number off hand, but how old is it?

For instance is it old enough that the electrolytics ought to be replaced with fresh ones of the appropriate voltage?

Would a woodchuck bother to chuck MDF?

i think it is manufatured in 1978.i am also not very sure.is there any chance of this type of oscillation if filter cap is bad.it is using two 3000/50v .it is a direct coupled amplifier in o/p stage.ifyou increase the base this oscillation increases
