Hybrid amplifier: Bipolar output stage, bipolar driver stage, vacuum tube gain stage.

• Zero global feedback, fully differential amplifier.

• Gain stage using one 6SN7 tube per channel.

• Stereo amplifier: 200 watts per channel into 8 ohms; 400 watts per channel into 4 ohms.

• Amplifier has a built-in high-pass crossover. 6 dB / octave, 16 settings from 40 Hz to 200 Hz in approximate 10 Hz increments.

• Single-ended and balanced inputs.

• Direct input bypasses all crossovers and switching.

• Power supply uses two transformers and three chokes. The high current section uses a dedicated transformer and choke input power supply. The vacuum tube B+ power supply is choke input and discretely regulated.

• All aluminum chassis construction.

• Stainless steel cover for transformers prevents magnetic fields from interacting with sensitive audio circuits.

• Bus technology reduces power supply impedence between output devices.

• RS232 control.

• 12 V trigger.
