Low bleed technics scrap,beware always rusted sensitivity preset,very difficult to access!you just don't get hi-fi from de-amplifier circuits!with DDR boxes good.HW

Blutarmer Technicsschrott,vorsicht immer verrosteter Empfindlichkeitsvoreinsteller,sehr schwer zugänglich!Man holt eben kein HiFi aus Entstufenschaltkreisen!Mit DDR Boxen gut.HW

Such a bad review can only be written by someone whose ears are playing tricks. The A 903 is 1A! Grundig should have stuck with something like this, and with the 9000 series.  
+
Eine so schlimme Kritik kann nur schreiben, wem die Ohren Streiche spielen. Der A 903 ist 1A! Bei sowas hätte Grundig bleiben sollen, und bei der 9000er-Serie.

A switch corroded after 20 years is not the world. A bit of Teslanol Oszillin, and the world is back in perfect contact. And these Grundigs with the wooden side panels sound impeccable anyway.
+
Ein nach 20 Jahren korrodierter Schalter ist nicht die Welt. Etwas Oszillin von Teslanol, und die Welt ist wieder wunderbar am Kontakt. Und klingen tun diese Grundigs mit den hölzernen Seitenteilen ohnehin untadelig.

I've had the A-903 for about 20 years now and use it with the CD player, tuner and cassette deck (!) of the A-903 or 905 series and a Dual turntable. It gets everything out of classical, jazz and sometimes hard rock. The amp works and sounds as good today on my JBL HP 430 as it did on day one. Only the little light that backlights the selector switches once broke. I am still very satisfied and can only recommend the A-903.

The A-903 is a good sounding, valuable amplifier of the upper middle class. Good examples are currently (11/2011) for 60-150 euros to get. This is an excellent price/performance ratio. Standar defect is - as with the 9000 and 9009 series - cold solder joints, especially at the output board, as well as hardening heat conductive paste and (by the heat development) affected electrolytic capacitors. As a prophylaxis it is recommended to unscrew the hybrid power amplifiers and everything else that is connected to thermal paste, clean it and make it fit for the next 20 years. Changing the lighting bulbs is a bit of a fiddly job, especially as the type used there is no longer available. You have to use other bulbs, where you have to extend the legs. Hobbyists like to take LEDs and rebuild the whole thing, then it's quiet for all time. Apart from that, the adjusters used in the A-903 are of such high quality, that even in a 20 year old, well maintained unit, nothing has to scratch. I had already several in the hand, which run also today butter-smoothly and without scratching. A real HiFi tip at a low price! (OSi-12/2011)

It should be mentioned that the amplifier reacts quite sensitively when 4 Ohm speakers are connected to the 8 Ohm output. The high currents are quickly acknowledged by the amplifier with a total failure. The power amplifiers are still available, but this is annoying.
 
−
In case of emergency it is sufficient to connect two 3.9 Ohm load resistors in series to the speakers.
