DIY methods to repair/replace guitar amplifier parts

Tightening of essential hardware pieces of a guitar amplifier

Whether you use a guitar amp regularly or occasionally, you should check it periodically to adjust and tighten its essential hardware pieces.

  • Handle mountings, speaker mounting bolts, and handles
  • Screws or bolts mounting the amp speaker baffle going towards the cabinet
  • Speaker cable with slide-on connectors, which connect the cable to the amp speakers and positive/negative terminals
  • Chassis mounting nuts and mounting bolts responsible for holding the chassis to its cabinet
  • External machine screws and bolts, which hold the amp transformers to their chassis, as they lose from vibration with time

Guitar amplifier tube replacement

If you can access the amplifier tubes without removing their cabinet chassis, you may easily replace the tubes. However, the question is-

How long do amplifier tubes last?

Depending on the frequency of turning on or turning off the gear, amplifier tubes last for a minimum of 5,000 hours to a maximum of 10,000 hours.

Preliminary steps to replace the amp tubes

Before you should start replacing the amp tubes, you must switch them off and unplug them from the wall. By doing so, the tubes become cool for many hours before you touch anyone of them.

Burning guitar amplifier fuses

Do you find your amplifier burning through its fuses suddenly? You should try to replace the installed tube rectifier with a new one of the same model. Later, you have to pop in a fresh guitar fuse at the same rate. In most cases, the trick works well and the problem resolves without the help of professional services.
