In 1965 Lenco released the Lenco LAB 52 STEREO. The electronics was designed and produced by HEA Vienna. It is based on their St1/1 transistor amplifier. It used germanium transistors in the power stage and the small signal part was constructed with silicon transistors. It had a socket for a RIAA pre-amplifier VVSt101. It was built with the B 52 record player. Later on it was replaced by the Lenco 500.
