Power On Power Off


Hello Audio Community, 

I have an Audio Research power amp and preamp, both tube models.  When it comes to tube gear, I have been told not to leave it on for too long when not playing it, if for nothing else, to keep from wasting tube life.  I am sure there is some debate here, but that is not my question.  I would like to know what the consensus is on turning on and off tube gear.  Someone told me that after I power off the tube amps, I should wait for 15 minutes before I turn them back on to avoid damaging the amps or tubes.  Of course under normal circumstances, this is not an issue, but what about the less than normal circumstances such as A:B testing of a power cable, or other similar moments?  Should I always wait before switching a warm, but powered off amp back on?  Is the reverse also an issue?  Can I turn off a tube amp too quickly after turning it on?

I'm also interested in this question.  Might want to move it to the Amp-preamp section to get some replies.
