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?

To answer your question about playing music...yes .
Don't just turn it on and walk away , PLAY MUSIC !
Tubed equipment , as I have been told , need the electrical changes to aid in the break-in process .
I have not noticed a big change in electrical components resulting from break-in like I have from speakers .
And I agree about it taking @ 30 minutes to warm up for tubed equipment .
So if you only have short periods of time to listen ,tubes are the way to go . My SS phono stage needs at least 7 hours of on time for warm up and my SS amp even more .
Most people leave SS on continuously and turn tubes off when finished to save tube life .

Just another 2 cents worth .
