Power Transformers datasheet and documents for PAM-PT-30-54R
Power Transformers Overview
The PAM-PT-30-54R is a 30W power transformer manufactured by Pacific Transformer, designed for the Trainwreck amplifier series. It features a 120V primary winding and provides multiple secondary voltages including 570V, 6.3V, and 300V (no-load). The unit supports 300mA and 10A current ratings on specific taps and utilizes chassis mounting for installation.
Power Transformers Feature Summary
- Designed specifically for the Trainwreck 30 Watt amplifier architecture
- Provides high voltage plate supply via 570V secondary tap
- Includes heater and bias windings at 6.3V and 300V respectively
- Constructed for chassis mount integration
Power Transformers Applications
- Trainwreck 30 Watt guitar amplifier restoration
- Replacement for original Ken Fischer specified power transformers
- Audio equipment rebuilds requiring 30W power transformation
Power Transformers Procurement Notes
Verify part number suffixes carefully as they may indicate physical variations or packaging differences not affecting electrical function. Confirm compatibility with existing chassis cutouts and terminal pin configurations before purchase. Ensure the supplier sources directly from Pacific Audio Magnetics to guarantee authenticity of OEM components used in the original Trainwreck design.
Power Transformers Selection Notes
Select this model only when replacing the power transformer in a Trainwreck 30 Watt circuit. Do not substitute with output transformers such as the PAM-OT-30-54R which serve different impedance matching roles. Ensure the replacement matches the 120V primary requirement and secondary voltage specifications for proper tube operation.
Power Transformers Part Context
This component belongs to the Pacific Audio Magnetics line of transformers originally engineered for Ken Fischer's Trainwreck amplifiers. It serves as the power supply unit, distinct from the output transformer (PAM-OT-30-54R) which handles speaker impedance matching. The pair constitutes the core magnetic components for the amplifier's power stage.
Power Transformers Replacement Considerations
The original Stancor 3801 was replaced by Pacific Transformer units in later production runs. Verify that the replacement is the power transformer variant and not the output transformer variant.
