PDF reference for the 2SA1360 transistor, roughly 176 KB. The file is labelled a schematic, but naming it after one part points strongly to a datasheet. Under JIS rules the 2SA prefix denotes a PNP transistor intended for high-frequency circuits. Consult it to identify emitter, collector and base, check breakdown voltage and dissipation figures, and select a suitable replacement. Before relying on it, make sure the marking on the board part really reads A1360 and not a similar code.
