1PC HiFi NAC552 Preamplifier PCB Gold Plated Bare Board Base On Na-Im Circuit

Description: Product Details:This PCB does not contain any components, and the assembly drawings are for reference only. Taken from the main amplifier circuit of the NAC552 flagship front stage, with the same layout and wiring PCB size: 266x155 (mm) Special process: silk screen, matte surface, high imitation of the original machine Power supply requirements: plus and minus 12V dual power supply, 6 groups. Optional LM317&LM337 power supply. The early NAC552 power supply used LM317+LM337 voltage regulator module, and the later power supply used discrete DR module.
