- > When you touch your buttons, an electronics mutes the inputs of the power amplifiers, so there is no noise when you switch to the speakers!!! The mute function often remains ineffective due to the oxidized spring contact string built into the buttons. This also applies to the mains switch!!! < -

Dimensions (WHD) 440 x 115 x 240 mm / 17.3 x 4.5 x 9.4 inch
Notes 3 IC, 20-20000 Hz.
Features
Hi-Fi stereo amplifier with 8Ω output. Semiconductors: 3 ICs, 36 transistors and 21 diodes. Tuner, two magnets and a magnetic turntable can be connected to it. There is a headphone jack on the front panel. Balan, high and bass control and volume potentiometer are located on the front panel. The push buttons can be used to adjust physiological volume, mono-stereo switch, high and low-cut filter. Below the input selector buttons. The display is a two-line VFD panel. Next to it is the "Mute" button, which reduces this volume by 10 dB.
Frequency response: 10 to 40,000 Hz. Bandwidth: 20 to 20,000 Hz. Signal to Noise: From tape and tuner inputs: ≥58 dB; turntable input: ≥50 dB. Harmonic distortion: 0.06%. Intermodulation distortion: 0.2%. Transduction attenuation: 1kHz for tuner and tuner inputs: ≥50 dB; turntable input: ≥40 dB. 10 kHz for tuner and tuner inputs: 40 dB; turntable input: 30 dB. Output power: sinusoidal: 2x30 W; music: 2x50 W. Power consumption: max. 160 W.

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.
