Two stage 46 valve stereo power amplifier with 6AX4 valve rectified power supply.

Harnessing four 46 valves - one driver and one output per channel. Coupled via an interstage transformer to preserve signal quality beyond simple capacitor coupling. Each 46 has its own individual DC regulated filament power supply ensuring perfect optimum operating conditions and long life. There's no hum to balance here from inferior AC supply.

A separate choke rectified power supply with the highest quality film capacitors offers a ripple free, black background with huge dynamics. Easily driven direct from a DAC or pair with the 01A preamplifier for the very highest level of performance. Ideally paired with high efficiency speakers, this could be the last power amplifier you'll ever need.

Default Configuration

• 4 x 46 valves
• 4 x 6AX4 rectifier valves
• Coleman regulators for each filament DC supply with precision voltage adjustment via top mounted controls. DHT filament current draw can vary significantly between valves - adjustable regulation ensures low noise, great sound and long life for your valves
