The Integrated Amplifier which DENON supplied the track record and technology of the apparatus for pros etc., investigated musicality, and was developed.
The Darlington power transistor of U.S. Motorola, Inc., Inc. is adopted as a power amplifier part in the PNP-NPN pair, and it is circuit composition,It is the PNP-NPN Darlington power transistor symmetry excelled [ power transistor ] in the electrical property, and a whole page direct connection OCL circuit, and low distorted-ization is realized.
Moreover, by taking into consideration the stability of adoption of the Darlington transistor which are 55-200 degrees C and the collector loss 150W, and the temperature compensating of the heat dissipation effect and a bias circuit, Tj fully examines a safe operation domain (ASO), and is designed, and stable operation is realized.
The unguided Hy Rippl type chemical capacitor and the power transformer which made internal resistance small, pressed down the rise in heat, and also took the influence of the leakage flux into consideration from the quality-of-the-material side were made the power-source part, and it takes it.
