This is an 18V, three-terminal regulator housed in a TO-220 through-hole package. The device is marked “LM,” “340T-18,” and “QDT842.” QDT842 appears to be a lot or date marking, not the part number. Please verify pinout, electrical requirements, heat sinking, and application compatibility before installation. Only the component shown is included.\u003cbr\u003e\u003cbr\u003eDISCLAIMER\u003cbr\u003ePlease review all photos carefully. Vintage electronic components may show normal storage or handling marks.

NTE's NTE958 is an 18V, 1A positive TO-220 regulator with a 21V to 33V input range, a candidate cross-reference; the LM340T-18 was not confirmed on NTE's published list. QDT842 appears to be a lot or date marking. Confirm pinout, input range and heat sinking against the original circuit before substituting.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQ\u0026amp;A\u003c\/strong\u003e\u003cbr\u003eQ: What is the output of the LM340T-18?
