Introducing the Heritage Audio Silverr 47 Tube Microphone Preamp
By Front End Audio on May 20th 2025

Introducing the Heritage Audio Silverr 47 Tube Microphone Preamp! Heritage Audio has just announced the new Heritage Audio Silverr 47 Tube Microphone Preamp. The Silverr 47 is Heritage Audio's take on the unique preamp that served as the foundation for the fresh and furious British Invasion sound that conquered the world in the 60s. The Silverr 47 cleverly recreates the original design to serve as a stand-alone dual-channel mic preamp that nails the sound palette of one of the most revered preamps of all time. It's a rather simple, yet flavourful design that has been adapted to perfection for the needs of modern studios more than 60 years after its creation. Finally, one of the most sought-after tube preamps of all time is available in a convenient two-channel form, and at a price at a price that would have even been hard to believe in the 1960s.

As a unique Heritage Audio design feature, they have added a NO FEEDBACK gain position, which drastically boosts harmonic distortion to previously unavailable levels, turning the Silverr 47 into a one of a kind shaping tool. In order to nail the sound that defined an era, every channel of the Silverr 47 employs a carefully sourced pair of tubes: a NOS 6AU6 pentode for the input stage and a JJ E88CC for the output, and custom made input and output Lang Electronics transformers designed by Heritage Audio.
