Break in period

I have just acquired the Conrad Johnson CT5 preamp and CJ LP70S power amp. Would appreciate inputs /advice of fellow a'goners regd optimal break in period and is the break in period dependent on playback volume or amount of
gain. The reason I ask is coz a Stereophile review of the CT5(July 2006 ?)mentioned that the preamp was left in continous play mode for a week, that translates to 150 hrs.Given that i listen max 2hrs/day and more on weekends, that translates to a break in period of nearly 2 1/2 months !!
Have huge issues leaving the system running 24/7 coz of erratic power supply and neighbour's privacy etc
Would appreciate any/all advice
Cheers

I would consult conrad johnson they know their equipment best. I have a premier 350ss amp with the teflon caps and break-in was long 250+ hours. I listened to music and did nothing special for break-in. Leaving tube equipment on unattended 24/7 to me makes no sense and can be dangerous. If the equipment has a stand-by mode then I would utilize that function but I would not leave it fully powered up unattended. Just my thoughts

The last three pieces of CJ I owned did not make it to 150 hours. Forget break in, they all broke. Shipped back to Virginia at my expense.

if it sounds fine, don't worry about break in. critics have loaners for as long as some folks own components. cj always sounds great, broken in or not.

Tubes don't "break in" but may change slightly as they age. Everything does.
