Tube amps aren’t without fault, and like many refined instruments and machines, need periodic maintenance to perform at their best and prevent failures - just like changing your car’s oil and giving it a tune-up. With our cars, we understand that changing the oil every 3-4k miles is recommended to keep the car running as it should. However, with tube amps, we don’t have regular maintenance intervals. Despite this, it’s important to understand that maintenance still needs to be performed eventually in order to keep them running smoothly. A lot of questions arise about maintaining tube amps, since we have all been told of the danger caused by their lethally high voltages. With this in mind, here are a few points to keep in mind about tube amp ownership and maintenance.
