That amplifier board's been clicking for two days and you know it's the PNP doing the heavy lifting. The TIP32 is a silicon TO-220 PNP transistor rated for 40 W dissipation, 40 V collector-base voltage, and 3 A collector current. Hfe sits between 25 and 50 at 25 °C with a 1 A bias condition. Solder it in, clip the heatsink if your layout needs one, and power back up
