PCB Size: 12.5 × 6.7 cm. Fixing hole spacing 11.4 × 5.4 cm. Q2: 2SA1015, Vceo = -50V, Ic = 0.15A, β> 40, may also be other similar small power PNP transistor substitution, pinout PCB design is an equilateral triangle, so that better compatibility, install other models Note transistor distinguish pins.
