The first production of our company "Golden Middle" from Saint-Petersburg, Russia, was established in 1996.
We design and build our tube amps and transformers with a musician approach to science.
We try to discover entirely new tube operating characteristics to measure then to invent ways of using them in operating circuits of amplifiers with the sound we expected.
Let's make sound together!

Observe safety precautions when working with high voltage!

"Golden Middle" gives a limited warranty for all products:
