Damir; what does he mean by the statement that oscillation is not a class A affair?
Does that mean because SE runs in class A or A1 all the time then here cannot be oscillation conditions in that amp?
I don't understand the post; why can you only find the condition of circuit oscillation in grid stage that runs positive?
Should I never worry about that situation if I run an SE amp in class A?
Also he claims to have cured an oscillation by using grid stoppers and the unit sounded better; but then he goes on to say that there is no way to tell without measuring very carefully.
Why is it others on the net claim that a SS CCS can cause a condition of oscillation if the CCS circuit goes bad? But not with a VR tube CCS?
Thanks Bud for putting up with these questions.
