Full Guitar Amp Replacement Valve Kits Explained
Most “All Tube” guitar amplifiers like valve head guitar amps and valve combo guitar amps include a mixture of pre-amplifier valves, power output valves and rectifier valves (or tubes in the USA). The typical life of a guitar amplifier valve is 1000 hours. As the tubes all operate together the performance of all the valves will degrade as time goes by – factors which reduce the life are heat and vibration.
Buying a full replacement valve kit for your valve guitar amplifier is the best way to restore the performance of your amp. The full guitar amplifier valve sets listed below include all of the valves that are required. The valves are latest manufacture from factories in Europe, Russia and China. They are supplied fully tested and specially chosen for their sound characteristic and saved into matched sets. Some kits include the rectifier valve however if the kit does not include the rectifier valve these can be purchased separately as they do not need to be matched.

Why Change all of the Valves in Your Valve Amp?
Buying a full guitar amplifier re-valve kit will restore the performance of your amplifier to the original design standard. If you have owned your guitar amplifier from new then you will already know if the valves have been changed however when buying a second-hand valve amplifier the age and usage of the valves may be unknown. In most valve guitar amplifiers the circuit will include matched power output valves are matched. Fitting unmatched valves may cause the amplifier to become unreliable with a noisy sound.
It can be a false economy buying single guitar amplifier valves and inserting them into the amp circuit. If unmatched valves are used in the amplifier it is highly likely that the output sound will be poor. Most likely using the valve amplifier like this will lead to expensive damage to other parts of the circuit.
When the amplifier is idle, both valves will draw a small amount of current. If both of the output valves are matched and drawing the same current, and have the same amount of gain, they will do a good job of cancelling any mains hum and other noise inside the amplifier circuit. If the are not balanced (or matched) more hum will be present in the speaker. Also, it is likely that there will be a mismatch in the current draw, resulting in one valve getting hotter than the other valves in the amplifier.
This may be severe enough to cause the valve to glow red which will reduce the life of the valve and overall reliability. Buying kits that have matched sets of valves will ensure the valves have been individually tested for the same bias current under identical conditions of plate voltage and grid bias voltage. If you are unsure about valve technology then read our Guide to How to Change Guitar Amplifier Valves.

Guitar Amplifier Tube Replacement
We have included some guidance on selecting the best new tubes for your guitar valve amplifier. Changing the valves periodically can have a massive effect on the quality of the sound generated by the guitar amplifier and also reduce hum. Read our guide to Amplifier Tube Maintenance and Care.
Once you have changed the valves in your amplifier make a note of the date. This can be by adding a sticker to the back of the amplifier. This will allow you to decide when is best to change them in the future. Amplifier valves (or tubes) will operate under normal conditions for up to 1000 hours. After this they will start to degrade.
