The Quad 303 is a two channel power amplifier primarily designed for high quality domestic installations. It is ideally suitable for driving loudspeakers in the 4-16 ohm range and will provide an output of up to 45 watts per channel depending upon the load impedance.

I use a Quad 44 pre and an FM 3 tuner (looking for an FM4). recently I bought twop upgrade boards for the 303s but I've not had the nerve to have them installed So there are people who say the 303 is the best Quad amplifier ever made. We don't agree if you use the 303 with modern digital source material combined with high volume settings. This is one of the reasons we advise to monoblock a 303 or use it in a bi-amp application per channel. The load dependent cross talk can influence the stereo soundstage Add Cx4, Cx5, Cx6, Cx7 470nF @ 250V MKT between each secondary and their respective centre tap (4 total) Change D7 bridge to CM2502 (25A, 200V) - Add D7' for second channel.
