What else to know about the A-50?

The A-50 is truly a genuine class-A operation stereo power amplifier built by Accuphase without any compromise, by pursuing its ideal for reproduced music. Thus Accupohnse incorporates its audio technologies that have be accumulated since its foundation as well as highest grade electronic devices that are available today. The advance of the class -A amplification method is that power fed form the power supply is always constant, regardless of the presence of the musical signals or not. This means that the amplifier exhibits high stability, while being subjected to no external interference. Thus the amount of heat generated from the output stage becomes extremely high. In general the power consumption os any class-A stereo power amplifier with a rated outpost of 50W is approximately 200W (about 350W in the has co the A-50) which is dissipated as heat. To counter this heat problem, the A-50 employee an exceptionally large heat sink for both the left and right channels to enhance the efface too the heat dissipation, thereby eliminating any double due to the concentration of heat in the internal circuitry.

Brief History of Accuphase

Kensonic Laboratory, Inc. had originally been releasing its products under the brand name Accuphase, but on the occasion of its 10th anniversary the company was renamed to Accuphase Laboratory, Inc., thereby unifying the brand and company name. The word Accuphase was adapted by taking the prefix ACCU from the word "accurate" and combining it with PHASE which is an important factor that relates to the innermost essence of audio technology. The unusual and somewhat difficult to pronounce name was a complete unknown in the beginning, and the company was often thought to be foreign rather than Japanese. In June 1973, one year after its formation, Accuphase moved to newly built premises in the Aoba district of Yokohama where the company is still located today. In August of the same year, the long awaited first models went into production: the separate power amplifier/preamplifier combo P-300 and C-200, soon followed by the AM/FM tuner T-100.
