Ausstattung & technische Daten
| Tecnical Details | |
| POWER OUTPUT | 75 watts per channel continuous from20Hz to 20kHz. 1kHz total harmonic distortion typically 0.6% at 75 watts, below 0.05% at 1 watt. Approximate actual power available at ‘clipping’ 76 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) 7Hz to 60kHz. |
| FREQUENCY RESPONSE | (-3dB points at 1 watt) 0.7Hz to 75 kHz. |
| INPUT SENSITIVITY | 1.4V RMS BAL for rated output. (25 dB Bal gain into 8 ohms.) |
| INPUT IMPEDANCE | 300K ohms Balanced. |
| OUTPUT POLARITY | Non-inverting. Balanced input pin 2+ (IEC-268). |
| OUTPUT TAPS | 8 ohms, 4 ohms. |
| OUTPUT REGULATION | Approximately 1.0dB 8 ohm load to open circuit (Damping factor approximately 8). |
| OVERALL NEGATIVE FEEDBACK | 15dB. |
| SLEW RATE | 10 volts/microsecond. |
| RISE TIME | 4.0 microseconds. |
| HUM & NOISE | Less than 0.06mV RMS – 112dB below rated output (IHF weighted, input shorted). |
| POWER SUPPLY ENERGY STORAGE | Approximately 520 joules. |
| POWER REQUIREMENTS | 105-125VAC 60Hz (210-250VAC 50Hz) 410 watts at rated output, 500 watts maximum, 230 watts idle. |
| TUBES REQUIRED | 2 – Matched pair KT150 – Power Output; 2 – 6H30 Driver. |
| DIMENSIONS | 19" (48.3 cm) W x 8.75" (22.2 cm) H x 19.5" (49.5 cm) D. Handles extend 1.5" (3.8 cm) forward. |
| WEIGHT | 47 lbs. (21.3 kg) Net; 63 lbs. (28.6 kg) Shipping. |
