Why Change Your Guitar Amplifier Valves
Guitar amplifier valves (or tubes as they are known in the USA) are robust and will work for many hours. Performance will be affected by mistreating them or allowing them to overheat. Generally the performance of vacuum tubes starts to degrades with the amount of time they are used and up to 1000 hours is typically the optimum life of a valve or tube. If the performance of your amplifier is failing then it is likely that some or all of the valves need replacement.
When replacing guitar amplifier valves it is best to use matched pairs as this will ensure the valves last as long as possible with the best sound quality. We have a full range of replacement guitar amplifier valves and matched sets available for the most popular amplifier types – see the links below.
