Chassis:
- All precisely machined anodized aluminum panels of 10mm and 3mm thickness,
assembled with machine screws
- Front panel – 4" high x 19" wide
- Main body: 22" deep x 18" wide x 3.625" high
- Overall dimensions with tubes installed: 10" high x 19" wide x 23" deep
- Weight – approximately 32kgs / 70lbs.
Low Frequency Power Amplifier:
- 100watt solid-state output module designed and manufactured by Bryston
- 500VA Plitron toroidal transformer
- 44,000 uF capacitance power supply filtering and energy storage
- Hyperfast soft recovery diodes
- Independent AC power fuse
Mid and High Frequency Power Amplifiers:
- Individual 300B output tube in single-ended-tube circuits with zero-NFB delivering 5watts before clipping
- conservative 20watts plate dissipation (only 50% of maximum) for long reliable tube life (10,000hrs+ expected)
- cathode bias for simplicity, reliability, and sonic quality - no adjustments necessary
- Sophia Electric mesh plate 300B supplied; all available 300B tubes are compatible
- Custom-made polypropylene film cathode bypass capacitors for superb transparency and musicality - superior to typical electrolytics
- Plitron toroidal output transformers
- custom designed by Menno Vanderveen for Aurum Acoustics
- optimized for higher frequency ranges - superior to transformers that must also run bass frequencies
- high impedance transformers provide the linearity of running the 300B at 40watts dissipation but without the tube stress and failure rate
- DC filament supplies using choke-equipped pi filters and high voltage supply with extensive choke-equipped pi filters and
cascaded filtering for the input sections
- noise suppressed to better than –80dB
- no adjustments required
- 6SN7 driver and input/crossover stages with zero-NFB
- optimized to match the 300B output stage for minimum distortion and optimal sonics
- screened and matched ElectroHarmonix tubes supplied
- customized polypropylene film coupling/crossover capacitors and precision metal-film resistors used in all related circuits including crossover functions
- Independent AC power fuse
Connections:
- Signal input – Cardas rhodium-plate RCA
- Internal wiring Cardas golden ratio, constant Q, crossfield, pure copper litz
- Neutrik 4-pin XLR with for mid and high frequency output
- a superior performer for this application that makes connections fast and easy
- internal wiring: Cardas SE golden ratio, constant Q, crossfield, pure copper litz
- Cardas Patented Binding Posts for low frequency output
- convenient single-knob clamping
- solid rhodium-plated copper contacts - perfect match to the Cardas spades used on the matching cable
- internal wiring is Cardas 9AWG golden ratio, constant Q, pure copper litz
- 15A IEC power inlet with integral RFI/EMI filter
- external power conditioners not necessary
- Accepts all standard 15A power cord connectors
- Aurum Acoustics optional power cord highly recommended
- All solder throughout the system is Cardas quad-eutectic with copper and silver content
