Specifications:

Description: Tubed stereo power amplifier. 

Tube complement: eight KT120 (matched pairs, output), four 6H30 (driver).
Input: Balanced, pin 2+ (IEC-268).
Output taps: 16, 8, 4 ohms.
Power output: 150Wpc (21.75dBW) continuous, 20Hz–20kHz into matched load.
Approximate actual power available at clipping: 160W. Power bandwidth: 5Hz–80kHz, –3dB.
Frequency response: 0.5Hz–120kHz, –3dB at 1W. THD at 1kHz: typically 0.6% at 150W, <0.03% at 1W.
Input sensitivity: 2.0V RMS for rated output,
Voltage gain: 24dB into 8 ohms. Input impedance: 300k ohms, balanced. Output polarity: non-inverting.
Output regulation: approx. 0.6dB 16 ohm load to open circuit (damping factor: approx. 14).
Overall negative feedback: 14dB. Slew rate: 13V/µs.
Risetime: 2.0µs.
Hum and noise: <0.1mV RMS, 114dB below rated output (IHF weighted, input shorted).
Power-supply energy storage: approx. 1040 joules.
