PAM-PT-18-31RZ

Power Transformers Overview

The PAM-PT-18-31RZ is a toroidal power transformer manufactured by Pacific Audio Magnetics, designed as a vintage replication of the Marshall 18 Watt power transformer. It operates at 60 Hz and features a primary voltage rating compatible with standard mains input. The unit includes specific color-coded leads for identification: white for the primary connection and red for secondary outputs. This component serves as a critical power supply element in tube amplifier circuits, providing the necessary high-voltage DC conversion after rectification.

Power Transformers Feature Summary

• Vintage replication design specifically engineered to match historical Marshall 18 Watt amplifier specifications
• Toroidal core construction for efficient magnetic coupling and reduced electromagnetic interference
• Color-coded lead configuration (white primary, red secondary) for simplified installation and wiring verification

Power Transformers Applications

• Restoration of vintage Marshall 18 Watt guitar amplifiers
• Custom tube amplifier builds requiring authentic power supply characteristics
• Professional audio equipment repair involving Pacific Audio Magnetics components

Power Transformers Procurement Notes

Verify the exact part number suffix against manufacturer documentation to ensure compatibility with specific circuit revisions. Confirm primary voltage requirements match the target application's mains supply. Check for physical dimension constraints within the amplifier chassis. Ensure the supplier provides official datasheets or specification sheets for technical validation before integration into sensitive audio equipment.

Power Transformers Selection Notes

Select this transformer when authentic vintage performance characteristics are required for Marshall-style amplifiers. Compare physical dimensions against existing chassis space to ensure fitment. Verify that the toroidal form factor aligns with the desired acoustic and electromagnetic noise profile. Consider the availability of replacement parts if maintenance is anticipated during the product lifecycle.

Power Transformers Part Context

Pacific Audio Magnetics specializes in custom audio transformers for tube amps, pro audio, and broadcast applications.
