The Electro-Harmonix 7591s Tube NOS is made with New Old Stock (NOS) tubes, which means that the tubes are brand new, but they have been in storage for an extended period of time. This process of aging gives the tubes a unique character, often delivering a softer sound and increased reliability compared to newly manufactured tubes.
The 7591s tube features a glass envelope, which is filled with a mixture of gases and a filament coated with a metal compound. When an electrical current is passed through the filament, it heats up, causing the gas inside the tube to ionize, creating an electrical signal. This process is responsible for the distinctive sound that tubes produce.
