The band is in full flight, the crowd is getting in behind and starting to respond to the music, the lead guitar player steps up and starts shredding, to the audiences delight. There is bang and a small cloud of smoke is ejected from the guitar player's amp and the instrument falls silent. It's time to seek the services of the amplifier repair person.
Classical music is echoing through the halls of a large prestigious residence when suddenly it is cut short by a loud incongruous crackle emitted from the inbuilt ceiling speaker system. The home owner relaxing in the lounge nearly drops his glass of fine red wine on the white shag pile carpet as the expensive stereo amplifier hemorrhages.
The above are results of faults in two amplifiers used in completely different ways and bearing no resemblance to each other. Faults in the first scenario probably far outnumber the problem in the second, however the point being made here is that they can happen no matter where or what they are.
Instrument amplifiers can get bumped dragged dropped in the course of moving them from one venue to another. Some have been deliberately kicked over and thrown across the stage as part of a bands act. Players can also stress the electronics within the units by over driving them with distortion pedals in order to get the sound that they want.
However it is not possible to economically produce them to cover all the circumstances of their use. Some artists have deliberately destroyed gear at the climax of their act. Little can be done to protect the amp if this is the protagonist's intention.
This is obviously not the case in the second scenario. Very high quality amplifiers are often built using valves. An old technology but one that the music buff will swear by in order to get the warmth of sound they are seeking. Many instrument users also seek this technology for the sound they are after. Most of these players cherish their amplifiers and take good care of them.
Valves are more fragile that their more recent solid state alternatives. The valve is like a light bulb whose inner filament can easily break if shaken especially when hot. Valves also have a finite life and like a light bulb will need to be replaced when they blow. Other components in the circuit board can also fail over time and if the unit is situated in a dusty location then bridges between components can be formed and short circuits occur.
The consideration of cost needs to be taken into account for an amplifier repair. The relative cost of repair to replacement has definitely erred on the replacement side in recent years. This is due to the flood on to the market of cheap solid state Asian built units and the huge variety of amplifiers available. This makes getting replacement parts a nightmare. Hand built valve units are a different category as they are usually expensive in the first place so repair is often the most pragmatic option.
