Description from the seller
Synthesis Roma 753 AC – Stereo Valve Integrated Amplifier
Excellent opportunity to acquire a Synthesis Roma 753 AC, a stereo vacuum-tube integrated amplifier of Italian manufacture, presented in excellent condition and fully functional.
The unit is equipped with TAD EL34 power tubes, delivering the characteristic rich, dynamic, and musical sound associated with valve amplification. The Roma 753 AC combines careful construction, high-quality output transformers, and a push-pull configuration in class AB, offering 50 W RMS per channel.
The amplifier also includes its infrared remote control, allowing you to adjust the volume, select inputs, mute the unit, and control the standby mode.
The Roma 753 AC is particularly appealing for high-fidelity systems, delivering a detailed, dynamic, and natural sound presentation with the musicality typical of EL34 valves.
Condition:
Excellent overall condition. It shows only very light marks compatible with its age and use. Technically it is functioning perfectly.
Valves:
4 x TAD EL34 – power tubes
4 x ECC82 / 12AU7 – input and driver tubes
Technical data:
• Type: Stereo valve integrated amplifier
• Configuration: Push-Pull Pentode
• Operating class: AB
• Power: 50 W RMS per channel
• Output impedance: 6 Ω
• Frequency response: 20 Hz – 20 kHz ±0.5 dB
• Total harmonic distortion: 1% at 1 kHz at full power
• Signal-to-noise ratio: >90 dB, A-weighted
• Input impedance: 50 kΩ
• Input sensitivity: 300 mV
• Inputs: 5 x stereo RCA line inputs
• Output: Pre-Out with variable level
• Power stage: 4 x EL34/6CA7
• Input/driver: 4 x ECC82/12AU7
• Bias adjustment: manual and independent for each power valve
• Output transformers: Hi-Grade Iron-Silicon
• Maximum consumption: approximately 250–300 W
• Remote control: included, via RC5 infrared
• Command functions: volume, mute, input selection and standby
• Power supply: 230 V / 50 Hz
• Dimensions: approximately 410 x 330 x 260 mm
• Weight: approximately 20 kg
Additional features:
• Carefully selected and matched valves
• Stabilized DC heater circuits in ECC82 valves, contributing to very low noise levels
• Gold-plated ceramic sockets
• High-quality speaker-terminal posts
• Rigid mechanical construction to reduce vibrations
• Original remote control
A meticulously crafted Italian valve amplifier with a 50 W per channel output and a highly sought-after EL34 push-pull configuration among hi-fi enthusiasts.
It will be properly crated for transport.
