SJS Arcadia Model 6 MM RIAA phono amplifier

We are pleased to announce delivery of the first of a new batch of the SJS Arcadia Model 6 MM RIAA phono amplifiers.

These feature the same basic power supply philosophy and circuit design, while the valves have changed to 6012 and 6112 dual triodes, each in an SRPP gain stage, providing high gain, linearity and drive ability.

The Arcadia Model 6 mm riaa phono amplifier is based upon the 6112 and 6012 NOS military valves, and a GZ34 valve rectifier, and has been specifically engineered for sonic performance rather than technical specification, and fulfils all SJS Electroacoustics primary design criteria:

• Single Ended circuit topology
• Pure Class A operation
• Zero negative feedback
• Valve rectification and choke-input HT power supply
• Custom made HT T-network power supply capacitors with silver leads
• Point-to-point circuit wiring without PCBs
• Hand built
• PTFE board for component mounting
• High quality components throughout
• Custom made aluminium chassis 

Bespoke customisation of the internal components is possible to meet our clients' specific requirements, whether it is replacement of the Duelund copper foil JDM capacitors or possibly using Tantalum film resistors, for example, these can be discussed at the point of ordering.

Here we have a bespoke customer order which includes a pair of Hashimoto HM-7 moving coil step-up transformers installed within the Model 6 chassis. Additional sockets at the rear provide for switching between MM or MC inputs, and also switching between low and high gain wiring for the HM-7 transformers.

Each amplifier comes with 2 years parts a labour warranty, except for the valves which have a 6 month warranty.

SJS Arcadia amplifiers are available from Definitive Audio in Nottingham.
