We do not test or screen the preamp tubes in house. All screening and testing would be done by the manufacturer.

How is the life span of this Mullard?
Asked by Anonymous on September 6th, 2017.
Tube life will depend on how frequently you use your equipment and total hours of operation. Unfortunately we do not have any specs on how many hours this tube will last.
