Model VS115

Specifications

POWER OUTPUT: 120 watts per channel continuous from
20Hz to 20kHz. 1 kHz total harmonic distortion typically 0.5%
at 120 watts, below .05% at 1 watt.
Approximate actual power available at "clipping" 130 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) 10Hz to 100kHz.
FREQUENCY RESPONSE: (-3dB points at 1 watt)
0.8Hz to 100 kHz.
INPUT SENSITIVITY: 1.6V RMS Single-ended or Balanced
for rated output. (26dB gain into 8 ohms.)
INPUT IMPEDANCE: 150K ohms Single-ended, 300K
Balanced.
OUTPUT TAPS: 8 ohms, 4 ohms.
OUTPUT REGULATION: Approximately 1.2dB 8 ohm load to
open circuit (Damping factor approximately 8).
OUTPUT POLARITY: Non-inverting. SE or BAL PIN 2+
(IEC268)
OVERALL NEGATIVE FEEDBACK: 12.2dB.
SLEW RATE: 10 volts/microsecond.
RISE TIME: 4 microseconds.
HUM & NOISE: Less than 0.2mV RMS – 104dB below rated
output (IHF weighted, input shorted).
POWER SUPPLY ENERGY STORAGE: Approximately 332
joules.
POWER REQUIREMENTS: 105-125VAC 60Hz (210-250VAC
50Hz) 690 watts at rated output, 900 watts maximum, 400
watts at "idle" .
TUBES REQUIRED: 4 – Matched pair 6550C – Power
Output; 4 – 6H30 gain and driver.
DIMENSIONS : 17.5" (44.5 cm) W x 7.9" (20.1 cm) H x 19"
(48.3 cm) D. Rear connectors extend .88" beyond chassis.
WEIGHT: 62 lbs. (28.2 kg) Net; 70 lbs. ( 31.8 kg ) Shipping.
