Notes This was "The home unit in Japan", which also incorporated a low power built-in FM transmitter controlled by a toggle switch on the top of the radio. In 1973, it was one of the first models in which a FET RF amplifier in FM band was used, which fact was reflected in proper wording on the top of the radio. Apart from 7 transistors (with two 2SB415 germanium transistors in the AF output stage, mounted on a large aluminum heat sink to produce 2.6 watt of audio), there are also three silicon monolithic IC's (TA7104P, TA7105P, and TA7064P) inside the radio. RF and IF stages of the receiver are made on separate PC boards called "Function Units", which are then mounted on the main PC board of the radio.

List of the transistors used in RP750FT: 2SK19 (FET, in FM RF amplifier)), 2SC380, 2SC373 (XC-373 as per circuit diagram), 2SC372, 2SC732, and coupled pair of Ge output transistors 2SB415.
