The key to building a truly magical amplifier is to maximise the dynamics in the signal and minimise any corruption in the process of amplification. Graham's designs are very concise, using the shortest possible signal path. The Discovery, rated conservatively at 8 watts, is constructed with three carefully divided partitions to eliminate the disruptive effect of magnetic, mechanical and electrical fields for the critical aspects of the circuit. The amplifier is built around the famous 300B valve, has only three resistors in the circuit and not one capacitor in the signal path. All the components are hard wired and of the highest quality available as well as being oriented to limit interference. Most are specially made to order like the strip wound C core transformers and chokes that are all hand wound. This guarantees perfect pitch, tonal colour, timing and harmonic structure of the music, where lesser components corrupt the signal. All this combined with the expert hand craftsmanship of a master of his trade (the Discovery takes over 200 hours of skilled labour to construct) brings you an amplifier like no other.
