In 1967 Lenco released the Lenco 500 Stereo. The electronics was designed and produced by HEA Vienna, using their St 1/3 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 like its predecessor LAB 52 Stereo. During the production Lenco used different cartridges: Ronette BF 40, Ronette Stereo 107, Shure M 75 MB and Goldring G 800. The original speakers were the Lenco 1928. First series did not have a headphone socket.
