In common with other SJS Arcadia amplifiers it has been specifically engineered for sonic performance rather than technical specification, and fulfills SJS Electroacoustics primary design criteria:
Single Ended circuit topology
- Pure Class A operation
- Zero negative feedback
- Valve rectification and choke smoothed HT power supply
- Custom made HT T-network power supply capacitors with silver leads
- Separate mains transformers for HT and filament supplies
- Point-to-point circuit wiring without PCBs
- Hand built
- Real solid wooden frame
- 4mm aluminium panels, black or natural anodized
- Soundcare SuperSpiked feet
The Arcadia Model 5 power amplifier is a modern implementation of the classic 6SN7-6SN7-300B topology with a few tweaks, mainly in the psu design, component selection and layout.

Design Options
The Model 5 SE 300B power amplifier is hand built to order in England, and therefore we are able to offer customisation to meet your aesthetic and sonic preferences. The solid wooden chassis is available in a range of four standard choices; cherry, maple, light oak and walnut with others such as zebra wood available to special order. The chassis panels are available in either natural or black anodised aluminium as standard, with other colours, such as blue, red or gold, available to special order.
Bespoke customisation of the internal components is also possible to meet our clients' specific requirements, whether it be for use of a certain interconnect cable between the phono sockets and the circuit, or replacement of the coupling capacitors, power supply capacitors or resistors, for example, these can be discussed at the point of ordering.
Each amplifier comes with 2 years parts a labour warranty, except for the valves which have a 6 month warranty.
