PAM-PT-50-11RZ

Power Transformers Overview

The PAM-PT-50-11RZ is a 50W power transformer manufactured by Pacific Transformer. It features primary windings rated for 100V, 120V, 220V, 230V, and 240V inputs. The secondary configuration includes a 660V winding and a 6.3V winding. Current ratings are specified at 240mA for the high-voltage secondary and 4A for the low-voltage filament secondary. The unit is designed for chassis mounting.

Power Transformers Feature Summary

• Supports multiple primary voltage inputs including 100V, 120V, 220V, 230V, and 240V.
• Provides dual secondary outputs with distinct current capabilities for plate and filament supplies.
• Constructed for secure chassis mounting in audio equipment enclosures.

Power Transformers Applications

• Fender Tweed Bassman amplifier restoration
• Tube amplifier power supply replacement
• Audio equipment chassis integration

Power Transformers Procurement Notes

Verify the specific pinout and physical dimensions against the target amplifier chassis before installation. Confirm that the primary voltage requirements of the destination equipment match one of the supported input voltages (100V, 120V, 220V, 230V, or 240V). Ensure the chassis has adequate space for the transformer's footprint and mounting holes. Cross-reference the secondary wire colors and lengths with the original schematic to ensure proper connectivity during assembly.

Power Transformers Selection Notes

Select this component when replacing a failed power transformer in a 50W tube amplifier circuit requiring specific 660V and 6.3V secondary outputs. It is suitable for applications where multi-tap primary voltage flexibility is required for international use or variable line conditions. Consider the chassis mount form factor and verify that the 240mA and 4A current ratings meet the load demands of the vacuum tubes in the design.

Power Transformers Part Context

Pacific Transformer produces custom magnetics for audio applications. This model is specifically associated with vintage-style guitar amplifiers, such as the Fender Tweed Bassman. The product line focuses on providing reliable power conversion for tube-based audio equipment, ensuring compatibility with historical circuit designs while offering modern manufacturing standards.

Power Transformers Replacement Considerations

Direct substitutes may include other Pacific Audio transformers with identical electrical specifications and mounting configurations. Verify pin-to-pin compatibility and physical size constraints within the amplifier chassis before finalizing the replacement part number.
