The PCB (8g) is permanently soldered to the motor. It features 2 momentary switches, controlling the on/off function and 'boost' function. There are also 2 ceramic capacitors, a transistor, a 'Tenta" safety capacitor, and 2 LED indicators

Length: 70mm

Width: 34mm

On the back side of the PCB features multiple diodes and resistors. There are signs of clear damage around the 'D5' diode leading from the mains 240VAC input. This may have been caused due to heat, leading to catastrophic failure of the device

The potentiometer daughterboard (<1g) is also soldered onto the main PCB
