About the 45
The James Burgess 45 amplifier is a custom-built single-ended triode (SET) amplifier designed for audiophiles seeking high fidelity sound. It uses 45 tubes and is often paired with 2A3 tubes in switchable configurations. The amplifier features a tube rectifier such as 5AR4/GZ34 or 5V4, a replaceable slo-blo fuse for protection against shorts or blown tubes, and a replaceable IEC power cord. It is compact and weighs approximately 25 to 30 pounds, with dimensions around 14 inches wide, 12 inches deep, and 8 inches high including tubes. The output transformers are custom-made, often by Jack Elliano, to match the amplifier's design. The amplifier is highly regarded for its build quality and sound, often described as a 'bucket list' amp for enthusiasts. It was still being built as recently as 2024, indicating it is not discontinued.
