HiFi Studio 1 is portable boombox manufactured by Telefunken in around 1979. This player consists of 4 band radio (with LW, MW, SW, and FM), cassette player/recorder and with 2 × 30W audio power amplifier. Restored HiFi Studio 1 This unit is designed using both ICs and transistors. The receiver of this unit is built around TDA1047, TBA570 and BA1320 ICs. Tape player/recorder is mainly build using NPN transistors and special Telefunken IC and 4066 ICs are used to get Telefunken's proprietary HIGH COM tape noise reduction feature. The power amplifier of this boombox is transistor based and it uses a pair of TIP130 and TIP135 transistors in its final stage.
