The Sonic Life of Tubes

Tubes Asylum

Questions about tubes and gear that glows. FAQ

I have Audio Research equipment and have found that I should replace the SED 6550 power tubes at around 2000 hours, even though they still test strong. Replacing them restores the fullness, richness and magic of tube sound.
Should I also replace the small signal 6922â€™s and 12BH7â€™s while they still test strong? Do small tubes rated at 10,000 hours lose their magic at 5,000 hours? I always tossed the Russians at 5,000 hours but now Iâ€™m using expensive NOS tubes and donâ€™t want to be foolish.
