Videoton's second generation (RT-402) high-fidelity Hi-Fi tower amplifier. Additional features of the tower include Videoton RT 6303 S tuner, Akai AP-Q310 / C turntable, Akai CS-F210 tape recorder, VT DC 2550 speaker and SA7 stand.
Its predecessor is the VT EA 6380 S, which has changed a lot. Interestingly, when you touch the buttons, the electronics mute the amplifier so there is no noise or bump on the loudspeakers when switching on. Its amplifier includes BD809-BD810 high-purity transistors, but the same can be said of the other semiconductors used in the final phase. Despite its active use, the last bolt is in its original, flawless and scratch-free state, making this amplifier even more special.
