I am getting some new tubes for my amp, and I want to do a 24-hour burn in. How do I do that?
Do I turn it on but leave it on Standby for 24 hours?

Also, are there any benefits of doing this, anyway?

"...1. Connect amp to speakers...2. Plug amp in...3. Turn amp on...There is more? Really???!

Check bias if required.

I just did some reading on other forums that it gets rid of the harshness of brand new tubes.
Even so, no big deal, generally harshness would vanish somehow quickly and bass will get tighter. You can have the pleasure of knowing how a particular tube will sound in its lifetime.
