[QUOTE="HB13DISH, post: 552491, member: 262829"] According to the resistors code for 5% tolerance 333 = 33.3 Kohms 472 = 4.7 Kohm So the schematics is probably using the code for value and not absolute value. How is the tone being generated? Is it using a crystal oscillator or a resistor/Capacitor circuitry? Don't bin it. If the problem is on the PCB, you just need to find out which part is faulty.
