The blue metal film resistors may be replaced with gray carbon film resistors, and the gray carbon film resistors. It is also possible to replace it with a blue metal film resistor. It is the same effect.

3. After welding, please self-test, if the welding is not wrong, it can be successful. If the welding fails, we can only help you to check the problem. We can't guarantee that you can succeed in welding. This is why the factory production line needs maintenance. For the reason of the work, the electronic products are broken due to static electricity, because the positive and negative poles of the power supply are connected to the wrong burnt, because of the chance of problems caused by the soldering, the wrong position of the components, etc., etc., don’t always say that the board line is problematic. This board sells tens of thousands of people, and dozens of people have problems!
