Bring a substantial piece of tube-era electronics to your restoration bench or vintage parts collection. This open chassis features multiple transformer assemblies, metal component housings, installed tubes, and a wide mounting panel with a toggle switch and red indicator.
The layout and high-voltage markings suggest a vacuum-tube power-supply assembly, but its manufacturer, model, original application, and electrical specifications are unidentified. Tube-position markings include two 3B28 positions, VR-150, 6AU6, and 6L6. These markings do not independently verify every installed tube’s identity or condition.
Approximately 19 × 11 × 10 inches. Includes the chassis, installed components, and pictured wiring. Used and untested, with visible wear, discoloration, and oxidation. A candidate for an experienced restorer or component-salvage project, not a verified working power supply or audio amplifier.
Tube condition, transformer windings, output ratings, operation, and completeness have not been verified. High-voltage warnings are present. Do not energize the assembly without inspection by a qualified technician.
