Overview
The Baldwin 100523 tube power transformer model 15L56-4072 is a used pull sourced from vintage Baldwin tube equipment. This transformer delivers the multiple voltage outputs required for classic tube amplifier circuits, including B+ supply for power tubes and 6.3V/5V heater windings for tube filaments. Suitable for restoration projects, custom tube amp builds, and vintage audio system repairs.
Key Features
- Multiple secondary windings for B+, 6.3V heater, and 5V rectifier filament supplies
- Original Baldwin manufacturing with robust laminated core construction
- Pulled from functional Baldwin tube equipment and tested for continuity
- Compact industrial-style mounting with secure terminal leads
- Suitable for tube amp restoration and custom amplifier projects
Technical Specifications
Specific voltage outputs must be verified with multimeter before installation. The Baldwin 100523 transformer typically features:
- Primary winding: 120V standard household input
- Secondary outputs: B+ winding, 6.3V heater, 5V filament (verify with continuity testing)
- Original vintage manufacturing, circa mid-20th century
- Laminated core construction for audio-frequency response
Typical Applications
- Tube amplifier restoration and repair projects
- Custom tube amp builds using period-correct Baldwin transformers
- Vintage audio equipment power supply replacement
- Guitar amplifier and organ amplifier restoration
- Sound reinforcement and small audio system projects
