Tubes can be a Pandora’s Box or a rabbit hole, depending on your outlook. For many, the opportunity to alter and improve the sound of their amp by tube rolling, is one of the joys of owning a tube amp.

If this describes you, we encourage you to explore different tubes, and feel free to contact us with any questions you may have along the way.

Do LTA tube amps generate a lot of heat?

Linear Tube Audio amplifiers produce far less heat than traditional tube amplifiers.

The ZOTL technology allows us to run ⅓ the electrical current through the tubes than normal, which results in much cooler tube operation. You could leave your amp on for days and still comfortably place your hand on the top of an LTA amp (not the tubes themselves).

Heat kills, so this also extends the life of tubes, to somewhere in the 10,000 - 20,000 hour range. Ask any other amplifier manufacturer about tube life, and the answer will be 1,000-2,000 hours, tops.

The reduced heat also makes our amps more child- and pet-friendly.

How long should I expect my tubes to last?

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.)
