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".

Based on my experience, my recipe for the best:

You don't need the amp on but you want a source playing music going thru the pre. I also believe in cycling the pre (during this time), ie, on all morning/off for a few hours/on late afternoon-evening/off all night til the next morning.

Two of my CJ preamps have teflon caps (ART 3 and ACT 2.2). I liked them out of the box, really liked them after a few hundred hrs, loved them around 6 months (have no idea the hrs at this point), and have been "in love" with them from a year on. They just seem to get better with time.

Enjoy the trip.
