Phonoboy 639

previous page

The Lenco Phonoboy (Mk II) record player - The soft line design has altered to straight and clear lines. It uses now the Lenco V 121 Mono transistor amplifier with an integrated power supply and the Lenco 639 chassis. 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 still as ‚Phonoboy‘. Later it was replaced by the le petit prince.
