Ein schönes Beispiel für ein klassisches Stück Audiogeschichte aus dem goldenen Zeitalter der japanischen HiFi. Jeder redet von Marantz/Pioneer usw. aus dieser Zeit, aber Firmen wie Hitachi bauten HiFi-Systeme des gleichen Kalibers und der gleichen Qualität. Eine schnelle Suche auf Reddit oder AudioKarma zeigt Ihnen, wie beliebt und immer noch etwas unter dem Radar diese Stücke sind. Der SR-903 verfügt über die gleiche Technologie wie der SR-904. Der einzige wesentliche Unterschied sind die zusätzlichen VU-Meter beim 904. Dies wurde getestet und alles funktioniert einwandfrei. Der Klang ist satt und klar. Ich habe innen alles gereinigt, ohne zu tief zu graben. Ich habe es nicht komplett zerlegt. Außerdem habe ich alle Tasten, Schalter und Knöpfe mit Kontaktspray gereinigt, damit sie alle reibungslos funktionieren und wie sie sollten. Die Lichter sind alle stark und hell. Es gibt einige leichte Kratzer und ein paar Absplitterungen im Metall an einigen Knöpfen, alles sichtbar auf den Fotos. Diese sind alle sehr geringfügig und beeinträchtigen nicht die elegante Schönheit dieses stilvoll Stücks. Bitte bedenken Sie, dass etwas in diesem Alter bei guter Pflege viele Jahre lang einwandfrei funktionieren kann, Sie aber auch überraschen kann, und das manchmal ohne guten Grund. Berücksichtigen Sie dies also, bevor Sie bieten. Ich kann Ihnen sagen, dass es bei mir einwandfrei funktioniert und ich alle Funktionen getestet habe. Aber bei Vintage-Ausrüstung besteht immer ein Risiko. Privatverkauf:?? Der Verkauf erfolgt unter Ausschluss jeglicher Sachmängelhaftung.

Mehr infos auf Englisch: Hitachi Class G Stereo Receiver SR-903 (1977) The SR-903 is a great match for power-hungry speaker systems. The low power output stage of the SR-903 delivers 75 watts per channel RMS. However, during musical peaks, the high output stage automatically produces 160 watts per channel RMS to prevent clipping and distortion. The SR-903s other outstanding features include: Dual Gate MOS FET for high quality FM tuner Auto-lock AFC circuit High selectivity and low disstortion IF amplifier using ICs and 3 ceramic filters Quadrature detection Phase lock loop circuitry for FM/MPX circuit A ceramic filter, IC in AM Tuner Two large easy-to-read meters, Large-sized flywheel tuning knob, A newly developed high efficiency high power audio amplifier (named series E Amplifier) Nwe IC in the equalizer, Mid-range/treble tone controls, Electronic protection circuit, Hi and low filters, Tape dubbing, Two speaker syatems connection, Detent controls. Only Hitachi SR-903 has Class G, the very newst class in amplifier operation. Stereo review went on to explain that this exclusive circuitry uses a low power and a high power output stage operating together.. At low signal levels the lower power stage drives the speakers. The transition to the more powerful output transistors .. Takes place smoothly at the point where it, becomes advantageous to do so. The point theyre talking about, of course, is where certain portions of the music you listen to demand more than the rated output to sound like they should. So when your music really gets thrilling, Class G cuts into a standby amplifier. Then, for just a moment, the SR-903 can pump out a lusty 160 watts per channel - without clipping. As a wrap-up. Stereo review said Class G delivers much higher overall efficiency than a conventional device, and this brings immediate dividends … in reduced weight, size and power consumption. Just read what the experts had to say about the Hitachi SR-903. What really makes you sit up and take notice of this receiver is its fantastic power reserve. StereoMagazine It can produce a little more than 3 dB above rated power - that is, twice its continuous wattage rating on transient peaks without clipping, rivaling in this case the performance on many a superamp. … performance far exceeds what can be rightfully expected of a conventional 75 watts amplifier. The generous headroom contributes to a sense of ease, clarity and crispness. High Fidelity Magazine Specifications: Audio Section Min.
