SS Power Amp/Tube Pre--on/off


my solid state power amp(krell kst-100) takes hours to max its sound and more hours to sweeted its elevated highest octive. i would leave on almost all the time, but i can't figure out how to deal with my NOS tubed CJ pv11 pre-amp. other than disconnecting the interconects, how else might one safely leave on the power amp and turn the pre-amp off when not in use for more than 12 hours. it hits me as wrong to burn-out
NOS tubes that are becoming more rare and more expensive over time by leaving the pre-amp on all the time.

ANY THOUGHTS.....i can afford the $50 to $100 to burn out a pair of quality 12au7/ecc82's each year. i just would rather not and one day soon they won't be available or they will be $200 per pair. one of you brilliant engineering audiophile-types may have an answer or is one of those situations where you can't have your cake and eat it!

The amp being on and the preamp off should not burn the tubes (for example I leave my player and transport on 7/24 but turn off my tube amp, with a volume pot, off between listening sessions). Both should be grounded (either on or off) and I can't see the benefit of removing the IC's. I am not a very technical person, so perhaps there is something that I am missing.
