How long for tube break in


After installing a new set of EL34 driver tubes, I'm wondering, how many hours until I can expect them to sound broken in? I've just gone back to tubes from a SS amp, and I'm missing the dynamics I thought I'd regain. They seem to be coming back, but then I just wonder if I'm getting used to the change. I'm using an AR LS25 MKll pre amp and a pair of Quicksilver M-80's into some Vandersteen 2C speakers. I've got about 60 hours on the new EL34 tubes now, (Sovteks). Does anyone know how the Quicksilvers match up against the AR power amps, for tube bloom? I was using the Monarchy 100 mono blocks before.

Thanks,
David

Perfectly agree with the above. Tubes don't break in - they even "wear out" when working - so to speak. So after warming up, which is 30 minutes max they should perform to their fullest potency. Biasing is VITAL!
Good luck!
