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?

With tubes there's a run-in period. At first, some tubes are not very quiet. With a few minutes they start sounding better and more quiet.

No offense to Polk432 but I thought it was funny how he mentioned 1001 precautions about tube amps and then closes with "Have fun. Tubes are great". LOL. This is why I went away from tubes.

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.

Get a speaker ab switch so you won't have to swap cables!
