Internal rattles in EL34 tubes

Tubes Asylum

Questions about tubes and gear that glows. FAQ

I've been offered some vintage Euro EL34s to add to my stash. One of my tests with large tubes is to hold it up to my ear and give it a light wiggle. With some, I hear a light jingle, others...silence. How much of a concern should this be? I suppose in a guitar or bass amp, yeah, it could raise havoc, but in a home audio amp.....

My Jadis Defy-7 runs two six-packs of EL34s. I highly doubt all of those would pass the wiggle test... yet sounds fine

All the tubes test well.
