The photographed component is marked “A747A,” “marantz,” and “500.”\u003cbr\u003eThe A747A marking follows the Japanese numbering for the 2SA747A, a PNP power transistor made by Sanken as the complement to the 2SC1116A (NPN) in audio amplifier output stages. Confirm the required component designation against your equipment's service documentation before installation.\u003cbr\u003eVoltage, current, power dissipation, gain classification, and terminal assignments have not been independently verified for this exact Marantz-branded component and are not specified.\u003cbr\u003e\u003cbr\u003eNew condition. Photos show surface marks and discoloration on the metal housing. No electrical test results have been provided. Includes one transistor; no matched-pair claim is made.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCOMPATIBILITY \u0026amp; CROSS-REFERENCE\u003c\/strong\u003e\u003cbr\u003eFor service and restoration of vintage Marantz receivers and power amplifiers that use the A747A \/ 2SA747A output transistor. It pairs with the C1116A \/ 2SC1116A NPN transistor in complementary output stages; the matching Marantz-marked C1116A is listed separately. Verify the part number, pinout and service-manual designation before installing.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQ\u0026amp;A\u003c\/strong\u003e\u003cbr\u003eQ: Is this the same as a 2SA747A?\u003cbr\u003eA: The marking is A747A, which follows the Japanese 2SA numbering convention for the 2SA747A. It carries the Marantz house marking.\u003cbr\u003eQ: What is the NPN complement?\u003cbr\u003eA: The 2SC1116A (marked C1116A).\u003cbr\u003eQ: Which terminal is the case?\u003cbr\u003eA: On TO-3 transistors, the metal case is the collector.\u003cbr\u003eQ: Is it tested?\u003cbr\u003eA: No. It is sold as pictured.\u003cbr\u003e\u003cbr\u003eDISCLAIMER\u003cbr\u003ePlease review all photos and item specifics carefully before purchase.
