Background and history



The EMT 139st stereo phono tube equalizer amplifier was designed in 1959 (price in 1959 DM 700,--) as partner of the EMT 139 mono phono tube equalizer amplifier to fulfil the need of stereo sound reproduction with the professional studio turntables EMT 927 and EMT 930.  It was and is a professional state-of-the-art stereo phono tube equalizer amplifier with top quality in- and output transformers to amplify low level signals of dynamic (MC) cartridges to studio balanced line level (+6dB). The first version, EMT 139st, was provided with de-emphasis characteristics for DIN, NARTB and RIAA,  the second version, EMT 139st b, was (re)designed in 1963 with de-emphasis characteristics for NAB-RIAA-DIN 33/45, DIN 78, BBC and FLAT. The EMT 139st b was in production with EMT until 1967 after which it was succeeded by the solid state version EMT 155st.
