104 is the capacitor 104 * 6 is here there are six 104 = 0.1uF capacitor, 221 is 220pF capacitor, 220 and 330 is the resistance unit is ohm 104 * 6 means that these six places are welded 0.1uF capacitor, capacitor voltage are Is 50V
0.22 is 0.22R cement resistor
10 and 68R are 1W watt resistors 0.22R is 2W watts or 5W. 1uF-10uF polyester capacitors and electrolytic capacitors can be soldered. We use 4.7uF. Electrolytic capacitors should pay attention to polarity. 4.7K is large, and 2W or 5W can be used.
