Power Tubes

We start with the finest tubes from around the world, test and match each one under simulated operating conditions to the tightest, most demanding industry spec. Each power tube is subjected to MESA’s advanced tube testing system – nicknamed ROBO-TUBE. Developed by Aerospace Engineers to our demanding specs, only the highest quality and most consistent vacuum tubes are tested, hammer-tested, passed, matched and finally labeled with the MESA Engineering logo and color code. Then we back them with the best warranty in the business - a minimum of six months.
