The V 0105 amplifier module was used in the very early version of the Phonoboy 639 portable record player. Designed as a battery operated Ge-transistor amplifier, in the case of the Phonoboy 639, Lenco added a simple power supply with a transformer, two diodes and an electrolytic capacitor.

There is no official drawing of the AC power supply used in the Phonoboy 639 so I did my own.*
