Overview
The Hammond Manufacturing 154M is a filter choke designed for tube preamp power supply filtering, radio repair, and DIY restoration applications. It features an inductance of 2H, a DC resistance of 175 Ohms, and a maximum current rating of 100mA. The component supports a maximum voltage of 300VDC. This specific choke is engineered to provide effective noise suppression and smoothing in analog audio circuits and vintage radio equipment.
Feature Summary
- Provides 2H inductance for effective power supply filtering
- Designed specifically for tube preamp and radio restoration projects
- Supports up to 100mA current with 175 Ohm DC resistance
Applications
- Tube preamplifier power supply filtering
- Radio repair and restoration
- DIY audio circuit construction
Procurement Notes
Verify the specific electrical parameters (2H inductance, 175 Ohm resistance, 100mA rating) against your circuit requirements before purchase. Confirm that the 300VDC voltage rating is sufficient for your application. Ensure compatibility with existing chassis mounting or wiring configurations typical for vintage radio and tube audio equipment repairs.
Selection Notes
Select this component when a 2H inductance value is required for low-current filtering applications under 100mA. It is suitable for designs involving tube amplifiers or vintage radio sets where specific impedance matching and noise reduction are critical. Consider physical size constraints if replacing older components in enclosed chassis.
Part Context
This filter choke belongs to Hammond Manufacturing's line of passive electronic components used in audio and radio frequency applications. It serves as a key element in power supply stages, helping to smooth out rectified AC signals into stable DC voltages for sensitive vacuum tube circuits.
Replacement Considerations
No direct public substitute part numbers are confirmed in the provided documentation. When replacing, ensure the new component matches the 2H inductance, 175 Ohm DC resistance, and 100mA current rating to maintain circuit performance.
