About Q-tron

Q-tron Audio was founded in Sweden in 1976. The company is working with professional electronic design including vacuum tube technology. Q-tron designed and built their first vacuum tube power amplifiers already more than 30 years ago and has since then been continuously involved in research of tube audio circuit technology.

The current Q-tron product line up is a result of extensive research where we have tested and built many different amplifiers using different circuit technology. During this time we have used both traditional measurements and extensive listening tests in order to find the best circuits and components to use for our amplifiers.

Q-tron current product line-up is today produced in Japan and Sweden.
