Romulus v2 "Class AB" Integrated Amplifier

The design for Romulus originated as a high quality integrated amplifier at a price competitive with mass-produced established rivals and inevitability compromises were necessary in the selection of materials and components. Replacing or revising an amplifier with the reputation that Romulus established is no easy task when the product has such a renowned track record. In this latest incarnation Romulus comes of age as a no compromise individually hand built high-end integrated amplifier.

Among the many changes are redesigned output transformers including 4 ohm and 8 ohm outputs in addition to improved frequency response resulting from improved winding techniques. The new power transformer is combined with a new multi-rail power supply assembled on a separate printed circuit board that reduces interference effects to the audio circuits.

The unusual circuit technique ensures total symmetry around the output stage, this forms the basis of this amplifier and continues to form the basis of CR power amplifier products. Power tube sockets are hard wired to the circuit board to guarantee reliability and isolate other components from associated heat stress.

A front mounted 3.5mm socket for a MP3 player analogue input complements input sources. Five input sources are selected by high quality relays minimising signal path lengths.

Adjustment of tube biasing was an inconvenient operation previously, now the trim potentiometers are accessible through the top cover greatly simplifying a dealer’s or service technician’s task. A rear mounted 5-pin socket provides easy monitoring of tube bias setting.
