Overview

The  FRENZEL RD-47 "REDD Mike" microphone tube preamp is part of our "INSPIRED" line of products.  It was inspired by the classic vintage 1959 EMI REDD47 microphone  tube preamp that was used by the Beatles to record their early albums at the Abbey Road Studio in London, England...but the RD-47 is not a clone. Control features were added that were not available on the original preamp to provide more tone and level control. Exceptional clear warm tones produced by a classic EF86 pentode voltage amplifer driving a vintage ECC81 dual triode output with rock solid level control enhanced by  voltage regulators.


Standard Features

IBalanced XLR Input & Output Jacks isolated from chassis to eliminate eddy currents and hum.

DC on filaments to eliminate 60 hz hum.
