167R36

Overview

The Hammond Manufacturing 167R36 is a laminated core power transformer designed for chassis mounting. It features a classic vacuum tube configuration with a primary voltage of 115V and a secondary output of 26V center-tapped at 8A, delivering a total power rating of 288VA. The unit utilizes lead wires for connection and is constructed for filament and low-voltage rectifier applications.

Feature Summary

• Laminated core construction for efficient power transformation
• Designed specifically for vacuum tube filament and low-voltage rectifier circuits
• Chassis mount design with integrated lead wires for direct installation

Applications

• Vacuum tube amplifier power supplies
• Audio equipment requiring filament heating
• Low-voltage rectifier circuits in industrial machinery
• Classic electronic restoration projects

Procurement Notes

Verify the specific secondary voltage configuration (26Vct vs 36V) against your circuit requirements, as distributor listings may vary. Confirm that the lead wire length and gauge meet your chassis layout needs. Ensure the 288VA power rating aligns with the thermal management capabilities of your enclosure. Cross-reference the manufacturer datasheet to validate electrical parameters before integration.

Selection Notes

Select this component when a dedicated vacuum tube power supply is required. The 115V primary input suits standard North American line voltages. The 26V center-tapped secondary provides balanced outputs suitable for full-wave rectification. Consider the physical dimensions and mounting hole pattern to ensure compatibility with existing chassis designs. Verify insulation class and temperature rise ratings for safety compliance.

Part Context

This transformer belongs to Hammond's 'Classic' series, targeting legacy and high-fidelity audio markets. It replaces older transformers in tube-based equipment. The 167R36 model is distinct from other Hammond power transformers by its specific 288VA rating and dual secondary winding configuration optimized for rectifier bridges.

Replacement Considerations

Direct substitutes must match the 288VA rating, 115V primary, and 26Vct@8A secondary specifications. Hammond part numbers such as 167R36 variants or equivalent vintage replacements should be verified for identical pinout and mounting dimensions. Generic replacements may differ in core material or lead wire quality.
