Questions about tubes and gear that glows. FAQ

Re: Jolida integrated popped

Sometimes a small particle of metal or oxide will come loose inside a tube and cause a short, but then vaporizes and allows the tube to operate normally again. it seems like you are OK for now, but if this happens again then you should replace the pair of tubes on that side.

It might be smart to switch tubes (by the pair) between left and right sides now. Then if the problem recurs and is now on the other side, you'll know it is the tube and not the other circuitry on the original socket.

If there is a loudness imbalance between channels that wasn't there before the incident, then the tube is still bad and should be replaced.

New EL34s are not expensive (about $30 for a matched pair.)
