Resistor 220R, 0.5W

220 Ohm 0.25 Watt Carbon Film Resistor220 Ohm Resistor Schematic Symbol

Colour code Red, Red, Brown = 2,2 and one zero = 220 Ohms, also commonly written as 220R. 

In old schematic diagrams you may see Ohmic values like this written as just 220.  This was a rather confusing and lazy practice that generally disappeared in the 1970's, along with the Ford Anglia and 8-track cassettes.  There are two in the circuit.  R16 is used in conjunction with C12 100uF capacitor to isolate the sensitive radio frequency sections from the supply rail perturbations caused by the high currents driving the speaker.  The other, R13, is used to help set the quiescent bias current in the complementary class B push-pull output stage along with D1 and D2.
