Went to play diezel einstein amp and heard weird cracklings.
I narrowed it down to single red plating JJ KT 77.
Can I just assume it was the tube as Ive played this amp without a single issue for a year on these particular used tubes which have an unknown lifespan.
Or do I REALLY need to take it to a tech to have it all looked it.
I was hoping to buy a new quad and bias them up to see what happens but didnt want to risk amplifier damage.
Thanks!
