How to break in a tube preamp?


Please excuse me if this is a stupid question.
I want to break in a newer ARC tube preamp (ARC says 400-600 hours needed to run in new Teflon coupling caps, etc.) and am wondering if I can accomplish this without running my tube amp at the same time and avoid spent KT-120 power tube use. Can I only leave a digital source on repeat with the preamp on and actually "burn in" the unit or is that not fully running what needs to be run to accomplish "proper run in".

In the case of my Modwright LS100 I was told by Dan Wright that the caps etc in his require same length burn in as yours and that I need to play music, not just have it on
I recently purchased a Modwright Ls100 which has the same break-in period as your amp and was told by Dan Wright that I needed to play music for the caps etc to properly break-in, versus just leaving the amp on. Unlike Ahendler's experience I have noticed a significant difference in this amp as it continues to get "mileage"
