Preamp break-in


I just got my CJ PV11 recapped  with Teflon caps.  My question is: do they need break-in?
 If so, does it require that music be playing or just leaving the unit on without music playing?

I had a CJ ET3-SE and it took about 200 hours to break in the teflon caps. Have fun w/your CJ.
Thank you for the responses.
 I’m happy with the improvement with the caps already.
 I can only imagine how much better it will be after break-in!
Yes they need to play music, but the amps don’t have to be on. :)

Set the volume level to normal listening volume. 
Break in, you know it's happened when you find your self just listening to the music and your not thinking about it any more. Happy listening.
Recapping wasn’t cheap (about $1500,) but it’s probably the best investment I could have made.  Already hearing amazing improvement.
 Like I just bought a super expensive piece of equipment.
