Transformers & Chokes

Hammond
Hammond Manufacturing offers a full range of transformers, chokes and enclosures.
- Designed for drop in replacement of original units.
- Physically, parts were designed to look similar to original factory units (where possible).
- Material used & design specs. were kept as close as possible to the original part to preserve the stock "tone".
- See P-T290-FENDER-120-UP for upgraded 120 V transformers, P-T290-FENDER-240 for 240 V transformers
Warning: Not all amplifier models of the same name use the same transformer model.
