Specifications
Power Output: 75 watts per channel continuous from 20Hz to 20kHz. 1 kHz total harmonic distortion typically 1.5% at 75 watts, .05% at 1 watt.
Approximate actual power available at “clipping” 80 watts (1kHz). (Note that actual power output is dependent upon both line voltage and “condition” i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)
Power Bandwidth: (3dB points) 12Hz to 70kHz.
Frequency Response: (3dB points at 1 watt) 1.0Hz to 70 kHz.
Input Sensitivity: 0.55V RMS Singleended for rated output. (32.5dB gain into 8 ohms.)
Input Impedance: 52.5K ohms Singleended.
Inputs (5): 1, 2, 3, 4, 5 (Single Ended RCA connectors).
Maximum Input: 10V RMS (any input).
Output Polarity: NonInverting (any input).
Push Buttons: Volume up, Volume down (103 steps), Power, Input, Mute, Bias. All functions on IR remote control.
Output Taps: 8 ohms, 4 ohms.
Output Regulation: Approximately 2dB 8 ohm load to open circuit (Damping factor approximately 4).
Overall Negative Feedback: 4dB.
Slew Rate: 10 volts/microsecond.
Rise Time: 4 microseconds.
Hum & Noise: Less than 1.0 mV RMS 88dB below rated output (IHF weighted, Vol down).
Power Supplies: Electronically regulated Low and High voltage supplies for input stages. Automatic 40 sec. warmup/brown out mute.
Power Supply Energy Storage: Approximately 350 joules.
Power Requirements: 100125VAC 60Hz (200250VAC 50Hz) 400 watts at rated output, 600 watts maximum, 210 watts at
“idle’: 1.0 watt power off.
Tubes Required: 2Matched pair KT120Power Output; 2 6H30 driver.
Dimensions: Width 14.5” (36.8 cm) Height 9.25” (23.5 cm)
Depth 16.25” (41.3 cm) Rear connectors extend .88” beyond chassis.
Weight: 36.4 lbs. (16.5 kg) Net; 49.3 lbs. (22.4 kg) Shipping.
