Trying to fix a broken stand mixer
yes. This is one of those ciruits which powers directly from mains, with no isolation transformer. Not so nice, but common on cheap electronics where the equipment body is all plastic.
Be very careful working on it, because you can have high voltages in the circuit even after you power off, due to charge stored on the capacitor!
A common problem in these circuits is either the rectification diode or especially the smoothing cap (large grey one by the look) which sometimes die after many years due to high voltage stress.
If you replace the cap make sure you use one rated for direct mains connection!!
