In 1965 Lenco released the Lenco LAB 52 STEREO. The electronics was designed and produced by HEA Vienna. It is based on their St 1/2 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. In Austria it was also sold as Donauland Studio 1000 stereo. The same amplifier module was also used in the Lenco 668. Later on it was replaced by the Lenco 500.
