The Lenco 639 record player -. The soft line design has altered to straight and clear lines. The loudspeaker is mounted in the topcover. It uses the Lenco V 121 Mono transistor amplifier. To save weight Lenco re-designed the motor and added an extra coil for the amplifier power supply so no extra transformer was necessary.

The Swiss distributor Ex Libris sold it in 1972 as ‚Phonoboy‘. Later it was replaced by the le petit prince.
