  • Type: Power amplifier
  • Years of manufacture: 1977 - 1980
  • Made in: Japan
  • Power consumption: 820 watts
  • Dimensions: 420 x 166 x 300 mm (WxHxD)
  • Weight: 19.2 kg
  • Original price approx.: 730 US-$ (1979), 2'200 DM


Technical data:

  • Direct-coupled DC amplifier circuit: yes
  • Output power: 2x 100 watts into 8 ohms ( 20-20 khz)
  • Frequency response: DC-100 kHz +0/ -1 dB
  • Distortion factor: 0.05 % at 8 ohm under 100 Watt
  • Distortion factor at under 10 Watt: 0.007 %
  • Power bandwidth: 5 hz - 30 khz (distortion 0.02 %, IHF)
  • Low pass filter: 18 hz
  • Attenuation factor: >75 (20-20 khz)
  • Input sensitivity: 1.0 V / 50 kohm
  • Signal-to-noise ratio: 116 dB (IHF)
  • Intermodulation at 8 ohm: 0.05 % under 100 Watt
  • Loudspeaker impedance: 4 - 16 ohm
  • Component: 41 transistors, 13 diodes, 2x FET (2-in-line construction)
  • Input level control: yes


Remarks[edit]

  • With the 3030 Laboratory Series, JVC showed in Europe in 1978 what was "state of the art".
  • High quality design, excellent characteristics and on the accompanying preamplifier 3!!! Connections for turntables.

The only small drop of bitterness is the missing headphone connection. Interesting was also the possibility to use 3 identical power amplifiers via a crossover. However, this procedure seems to have never prevailed, especially in Europe.
