How do I break in a tube amplifier?


I should be taking delivery of my Yaqin MC-30L tube amplifier this weekend. I believe the dealer is going to set it up and bias it and may even let it run for a few hours before I pick it up. It's going to be a 2nd system sharing speakers with my primary home theater system so I will have few opportunities to leave it running for extended periods of time.

Does it do any good to just leave the amplifier turned on or does it actually need to by playing music?

The amp I'm getting has a soft start feature.

Any major issue connecting my receivers pre-outs to the tube integrated other than having two volume controls? I'm exploring options for not having to swap speaker cables back and forth as much.
Wolf ..., ARC told me the same about waiting 5 minutes between a shut off and restart. But you asked a good question about where one should wait during the 5 minute cool off period.

I was told that I should wait in another room and that I must NOT look at the amp during the 5 minute cool down period. Otherwise, the amp may not start up again. So I wait upstairs and lock the basement door for 5 minutes. Doesn't everyone???

LOL ;>')
My god; you can leave it unattended whenever you wish. I mean, I wouldn't drive off for the day while it's on, but I've left my ARC or Sophia or BAT on for hours while I'm otherwise occupied.

Just make sure small children aren't around it.
