EMT 139st # 4566 from 1959 & EMT 139st b # 8036 from 1963


the legends

My private collection contains all versions of EMT phono equalizer amplifiers for the EMT 927 and EMT 930, mono as well as stereo, tube as well as solid state. Two highlights are the legendary stereo phono tube equalizer amplifiers EMT 139st with serial no. 4566 from 1959 and the EMT 139st b with serial no. 8036 from 1963.

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.


The EMT 139st and EMT 139st b in my collection are still in complete original state, they are only cleaned and no restorations or modifciations are made and, after more then fifty years, they are in great shape and superb working condition.
