New Tube Break-In


I just purchased two new RadioTechnique 12AU7's for my CJ PV10A (Any opinions on this match?) and I'm not sure if there are any break-in recomendations. Do you know of any or have any rituals of your own? Should I be able to play them loud and fast right away?

Thanks,

Advice from Upscale Audio:
"First time start-up and flashing lights - If your gear has filaments that are constant on, first install the tubes, plug it in according to manufacturers instructions, and let it sit for a few hours. I know you want to hear it right away but if there has been a small amount of gas that has developed since the tube was tested, it’s best to let it burn off before turning the tube all the way on."
