Tube amplifier repair is made easier when there is a checklist of potential problems to follow. Finding a solution to the problem is quicker when you check the problems that occur most frequently. When you follow a checklist you will have a track to follow so time is not wasted. Instead, you can discover the source of the problem quickly without going on a wild goose ride.
The amp should have a red small light which indicates that the power is turned on. If this light is not glowing then the first thing to check is if the amp is plugged into an electrical outlet. It is surprising the number of times that the unit is simply not plugged in. In rare cases the light is blown out, but chances are there is another problem.
If the unit is plugged in properly but the red light is still not on then the problem might be with a fuse. A blown fuse is a symptom of another problem which is the real problem that must be solved. The fuse might not be the appropriate rating for the equipment. Check to see if it is the right kind of fuse for that piece of gear. Replace the fuse with a fuse with correct rating. The power supply ought to be inspected to determine if it is functioning correctly.
There are many parts that can fail. Resistors, capacitors and other electrical parts may have failed and will have to be replaced. The input cords may have a short circuit or the tip may be damaged. All the cords, including cords hooked up in foot pedals and other effect devices, should be inspected. If you suspect a tube is the problem, replace it with a good tube and test the equipment. This can be a time consuming process if done thoroughly.
If the amp has a low level of power or the volume is low, may indicate that there is a bad preamp cathode resistor, phase resistor, rectifier, or power filter capacitors. The vibrato circuit ought to be inspected as well. A oscilloscope may be necessary to diagnose the problem.
If smoke is coming out of the equipment or if there is a burning smell, then the unit should be turned off and unplugged immediately. It should not be difficult to see which part was over heated because it probably will be charred. It is likely that another part is causing the problem by sending excessive power to the component that was overheated.
If you do not have the time or the skills to repair the equipment yourself, you should find a qualified technician. It can be difficult to trouble shoot a sophisticated electronic device. An experienced and qualified expert may be a better choice if you are not confident about your skills.
