Reference sheet for the 2SA1244 transistor in PDF form, 295 KB, listed as a schematic even though the name gives nothing beyond the part number and the file is most likely a datasheet. JIS numbering uses the 2SA prefix for PNP bipolar transistors. When a failed device is found in a power or audio stage, a sheet like this lets you verify absolute maximum ratings, hFE class and pin assignment. Choose any replacement by those figures rather than by the package alone, since similar cases can hide different pinouts.
