D DDad New member Aug 3, 2025 #1 I have an MXR headphone amp board and the marking on the board shows each transistor not as round on one side, but rhomboid with one side longer than the other. Is the longer flat side considered the flat side of the transistor?

D DDad New member Aug 3, 2025 #2 Ooops, just realized that board is from a different company. Anyone know the answer anyway?
Robert Reverse Engineer Aug 3, 2025 #5 Yes, as long as you are using the specified 2N4401 / 2N4403, the beveled side of the PCB silkscreen corresponds to the round side of the transistor.
