P10 Phono Amplifier

The P10 phono amplifier is intended to meet the requirements of audio enthusiasts who still enjoy the distinctive strengths and high quality of reproduction that can be derived from vinyl records.

It is compatible with moving magnet and high output moving coil cartridges, while low output moving coil cartridges will require the use of an additional step-up device or matching transformer.

The active amplification stages use double triodes in a simple anode follower configuration. The phono equalisation is achieved using passive components and can therefore maintain its accuracy over time without introducing the unacceptable levels of phase shift found in active equalisation stages.

There is no negative feedback in the circuit. The P10 features a particularly elaborate HT power supply. After the initial rectification and smoothing, the supply is split and two separate, heavily decoupled high voltage rails are established.

The valve filaments are also fed by a DC supply thereby ensuring constant operating conditions for the amplifier. The circuit makes use of close tolerance metal film resistors, polypropylene signal coupling capacitors and selected valves.

The gain of the P10 is 40 dB (x 100). The P10 phono amplifier meets the very strict performance criteria required of all puresound products and will give excellent results with vinyl records provided that it is used with appropriate ancillary equipment.
