Hi, I just re-tubed my Cary V12 and wondered if like other electonic components (cables, cartridges, etc.), do tubes have a break-in period? And if so how long till they sound their best?
Yes,tubes need a burn-in period of at least 48-hours. There is no need for a signal input. At the end of the burn-in period, the tube will have a better signal to tube noise ratio.
