In Reply to: Tube Breakin? posted by Lynn Epstein on September 25, 2002 at 09:14:05:
.....when you have equipment (ears too, and what's between them) that can't reveal the phenomenom of break-in. It does exist, but as with many things, in varying degrees.
With tubes, the chemicals and binders that make up cathode composition change when first put into service, a major reason for the change- it sounds different because it actually is. There are people that also greatly exagerate or embellish the differences as well. You simply have to decide for yourself, in your system, what really matters- keep in mind that tubes, as well as some other components have a possibility of changing significantly within a 100 hr period.
In other words, when you first put those new JJ/tesla el84's in and you can't stand them, but you leave the amps on for a couple days in the off hours just to see, and then you listen and....aaaahhh, so much better you can't believe they're the same tubes, well, now you know why sometimes you can't draw immediate conclusions like you did with some other brands. Which is why you have to be careful with recomendations, for or against anything- how did they evaluate? It took nearly 100 hrs for those JJ's to burn in, peeking in every 12hrs. to hear the progress- if you only listened for 2-3, you would have tossed 'em out (the Bugleboys sounded good, then great). And that's another thing, keep your stuff if you can, because systems change and that Mullard that sounded soft but just o.k., so you put it away, sounds really killer in that new tube cd player or preamp after just installing new caps & resistors, and after breaking everything in, sounds a little harsh. Systems change, everything changes- it's a law of the universe.
