A valve does not have a set life span. We normally recommend the power valves are replaced every eighteen months to two years, pre amp valves approximately every four years. When having your power valves replaced we recommend these are matched and the amplifier is re biased, regarding the pre amp valves these can be replaced individually as pre amp valves do not need biasing when replaced. All work of this nature must be carried out by a qualified engineer.
