ZOTL technology allows us to use ⅓ the electrical current than normal, which results in much cooler tube operation. This, in turn, extends the life of tubes, since it’s heat that kills tubes.
So, with LTA amps, you can expect tube life in the 10,000 - 20,000 hour range.
Depending on your listening habits, this could effectively mean you never have to buy another set of tubes again. (Although we know most of you won’t be able to resist trying out different tubes.)
Ask any other amplifier manufacturer about tube life, and the answer will be 1,000-2,000 hours.
The reduced heat also makes our amps more child- and pet-friendly.
