In late 1968 Lenco released the Lenco 350. The electronics was developed and produced by Lenco. All operating elements, with black plastic knobs, were on the left side. During production the knobs were replaced by plastic knobs with aluminum covers. It was built with the B 52 Mk I record player, equipped with a Ronette BF 40 ceramic cartridge. Original loudspeakers were the Lenco 1928. It was distributed in Switzerland by Ex Libris and sold for CHF 280.—.
