Tube Break in Period / Method


Just rolled out the Stock tube out of my Music Hall 25.3 DAC and replaced it with a NOS JAN Sylvania 6922. (Mullard was out of my price range) How long should I expect the break in period to be and what is the best method? Set a track on repeat or just leave the unit on?

Thanks,

John

You may notice a difference in the first 10 hrs. Then another in about 50. Hopefully they sound good right away and then just get better in that 50.

I don't think it's best to run it non-stop for the 50 hrs. I think it's better to cycle them. Run them for 4-6 hrs then let them completely cool before the next run.

Do have music playing thru them and vary the volume. Don't go real loud in the first hours.

Most important....enjoy.
