Lancashire based audio specialists Rothwell Audio Products Ltd have announced the release of their Signature Two discrete transistor moving coil phonostage, and within the phonostage itself, there are neither transformers nor op-amps resulting in a stunningly clear aural experience. It is the result of over twenty-five years’ experience in the design of these devices.
The four-stage unit uses discrete transistors operating in class A. Stage one is a low-noise circuit with adjustable load impedance from 32Ω to 1100Ω and variable gain from 52dB to 72dB with load and gain independently adjustable. Stage two precedes the highly accurate passive RIAA network. Stage three is another gain stage and stage four buffers the output for low impedance.
The on-board linear power supply uses a toroidal transformer, generous sized capacitors and another proprietary low noise discrete transistor voltage regulator. The carefully regulated supply to the first stage delivers extremely low noise and ripple, far lower than the common off-the-shelf monolithic alternatives.
Like all Rothwell products, the Signature Two is designed and built in the UK. Full technical specifications are available on www.rothwellaudioproducts.co.uk .
