The V 220 amplifier module was used in the Lenco twenty 656 VT, Lenco Twenty Star portable record player and in the Silvretta HF-TR* receiver. The design uses an additional input stage that has been omitted in the V 120, V 121 and V 122.
* HF-TR was a 6 channel RF distribution system that run over the telephone network from the Swiss PTT - the only Swiss telephone company at that time.
