A-G90B
The A-G90B was a Dynamic Super-A Stereo Integrated Amplifier manufactured by the JVC Corporation of Japan. The Super-A incorporates JVC's three most important technologies to reproduce the most accurate sound. This amplifier is 85-watts per channel (at 1 kHz DIN) when connected to 8 Ω speakers. It has the following features.
- 85-watts per channel
- Dynamic Super-A power amp for better in-use performance
- Gm Selector for low noise at average volume levels
- Gm Driver to improve speaker driving capability
- Input-capacitor-less high-gain phono equalizer for MM/MC cartridges
- Independent DAD terminals
