About us

Elfring Amplifier Manufacturing stands for high quality and service, for private persons as well as businesses. We manufacture prototypes as well as big quantities.

Owner is Floris Elfring, educated as aeronautical engineer and lover of guitar music. In 2007 his hobby became his business: he became co-owner of the Dutch brand Kool & Elfring and developed and manufactured several amplifiers and speaker cabinets.

After eight years he decided to share his knowledge with others. He knows everything about developing and manufacturing tube amplifiers and speaker cabinets. Being specialized in tube amplifiers does not keep him from designing, developing and manufacturing other electronic and wood products.

The products made by Elfring Amplifier Manufacturing stand out from others at high quality and finish.
