PAM-PT-135-20R

Power Transformers Overview

The PAM-PT-135-20R is a 135W power transformer manufactured by Pacific Transformer, designed for chassis mounting. It features a primary winding rated for 120V input and provides three secondary voltage outputs: 380V, 50V, and 6.3V. The corresponding current ratings for these secondaries are 500mA, 5.5A, and an unspecified value for the 6.3V rail. This component serves as a critical power supply element in high-fidelity audio equipment.

Power Transformers Feature Summary

• Provides multiple isolated secondary voltages for complex circuit requirements
• Designed for robust chassis mounting applications
• Engineered to replicate original equipment specifications

Power Transformers Applications

• Fender 135 Watt Silverface Twin Reverb amplifier restoration
• High-power tube amplifier power supply systems
• Vintage audio equipment repair and maintenance

Power Transformers Procurement Notes

Verify that the replacement unit matches the original physical dimensions and terminal configuration to ensure proper fit within the existing chassis. Confirm that the primary voltage rating aligns with the local mains supply to prevent operational failure. Cross-reference the secondary voltage and current values against the schematic of the target device to guarantee electrical compatibility before installation.

Power Transformers Selection Notes

Select this specific model when replacing a failed power transformer in a 135W Fender Silverface Twin Reverb amplifier. Ensure the new unit supports the required 120V primary input and delivers the necessary 380V, 50V, and 6.3V secondary outputs. Consider the chassis mount style if space constraints or mechanical stability are priorities for the assembly.

Power Transformers Part Context

This part belongs to the Pacific Transformer lineup specializing in vintage replication components. It is specifically engineered to replace OEM parts in classic American guitar amplifiers. The manufacturer focuses on maintaining historical accuracy in electrical characteristics and physical form factors for restoration projects.

Power Transformers Replacement Considerations

PAM-PT-135-20RZ is listed as a variant supporting international primary voltages including 100V, 220V, 230V, and 240V. Select this suffix only if the operating environment requires non-standard primary inputs different from the standard 120V specification.
