SOLID STATE STEREO Amplifier KA-4004 - 1972
Kenwood, Trio-Kenwood Inc.
Hi-ATC series integrated amplifier with enhanced characteristics only in the audible frequency band but also in the ultra-low range.
The all-stage direct connection + pure complementary circuit by ± 2 power supply system is adopted.
The transistor of the metal can seal is adopted as the first stage circuit and an equalizer circuit of an integrated amplifier.
Moreover, the metal film resistance of the low noise type nichrome vapor deposition is used for the first stage circuit, the equalizer circuit, and the tone circuit, and the secular change is suppressed.
