It depends on tube itself and the amplifier circuit it is plugged into.

No, a "Cayin K88" is a rebranded tube from another manufacturer. And I don't keep any figures in my head for life span of each tube in each amplifier. Circuits that provide for a soft start to the tube as it powers up make more difference than anything else other than bias. Bias is either fixed or user adjustable. How the manufacturer chose to deal with tube bias is something you cannot change.


I accept the fact tubes are not forever, they must be replaced. If you are concerned about tube life, you probably shouldn't be looking at or using a tube product.

My dealer once told me that a McIntosh representative told him that their tubes will last anywhere between 5 minutes and 5 years. I guess what that means is that like anything electronic, if it's gonna fail it'll likely fail right off the bat.

To put it another way, if he's worried about being without the amp, he should carry an extra set of tubes on hand.

How much do a set of tubes cost anyway?
