The PCB’s and the transformer were manufactured in Lenco’s own factory in Steg*. The V 425 module was installed in the Lenco L 350A record player. A further development lead to the V 425-S. For more flexibility the pre-amplifier and the power stage are now on two different boards. The power supply is stabilised with an medium germanium power transistor AD 162.
