Simple question, probably stupid


Is it necessary to have sound (music or white noise) playing through the speakers when burning in new tubes? I have bought a matched quad of Shuguang KT88 Z Black Treasure tubes to compare with my current Gold Lion KT88 and Tung-Sol KT120 tubes in a Rogue Stereo 90 amp. Reviews of the Shuguang tubes indicate that they need around 200 hours of burn in to reach their true potential but I am not looking forward to having to listen to 200 hours of crap sound.

Mho, there are no stupid questions, really.
Inspired to inane answers, yes. 

I've viewed 'break-in' as something that should be done with ss as well; 'conditioning' to a life of service...

I recall when for vehicles of any sort called for a break-in period of +/- miles before one did 'pedal to the metal', to let all the mechanicals 'seat 'n seal' properly.

How about a 'structured approach'?

10 hr. 'idle'; on with no signal....just warming up.
10 of white or pink noise, low volume.
10 of low volume program, 10 of louder, etc.

That allows for some degree of 'grats', even if not 'immediate'.... ;)

Can't hurt, might do the thing that's suggested without having to 'pause the Cause' for 100... ;)

Enjoy the 'arrival', J
