New power tubes will typically "freshen" up a sound which has lost some of it luster due to tubes of advanced age. But, whether your tubes need replacement depends on the hours. Tubes in you amp should probably last between 1500 and 3000 hours. If your past 3000 hours you probably should get new ones. One thing you could do, if you know how, is to rebias your tubes. That will usually let you know how worn your tubes are (badly worn tubes won't bias up properly) and if they don't need replacement, the rebiasing will improve the sound. Ideally, you should learn to do this yourself and do it every couple of months to get the best out of your amp.
When to replace 6550c on ARC VT 100 III
When should I replace the 6550c on ARC VT-100 III?
The unit is a little over 2yr old and is used often.
Will I hear a change in the quality of sound that indicates tube wear, or do you just wait for them to fail?
Will Fresh tubes sound better even though I don't detected any trouble?
