Transformers & Chokes

1600 Series

Hammond has been producing tube output transformers continuously for over 75 years, constantly improving and tweaking their performance. The output transformer is one of the most critical components in a audiophile amplifier. These excellent designs have survived the years and continue to provide great choices for replacement or new build applications.
P-T290-FENDER Transformer - Hammond, Guitar Amplifier, replacement for Fender
Replacement for Fender Champ, Vibro Champ, Princeton, Princeton Reverb, Tweed Deluxe Equivalent to Fender part number 125P1B & 022772 Primary:120 VAC, 60 Hz. For 240V version, see P-T290AEX Features:
  • Designed for drop in replacement of original units.
  • Physically, parts were designed to look similar to original factory units (where possible).
  • Plastic Core
  • Material used & design specs. were kept as close as possible to the original part to preserve the stock "tone".

Warning: Not all amplifier models of the same name use the same transformer model. Please make sure the amplifier transformer which you are replacing has a Fender number matching the equivalent Fender transformer number listed here.

P-TN-51X Transformer - Line Isolation, 35 VA, 115V, 300 mA, 1 x 115V
35VA chassis mount Power Transformer for isolating equipment from direct connection to the power line. It is constructed with non-concentrically wound coils. The primary and secondary are wound on separate arbors, then assembled on a laminate core side-by-side separated by insulation. This prevents electrical connection under normal or overload conditions between the primary and secondary windings. These units are designed with 1500V isolation between winding to winding and between winding and core. Materials and construction are rated for Class B insulation system.

P-H1600-A Switch - Rotary Impedance Selector, for Hammond 1600A series
Includes: 3 pole, 3 position rotary switch, ¼" output jack and black chicken head knob. Hammond 1600A series transformers provide 'easy wire secondary' impedances of 4, 8, or 16 ohms. We now offer a selector switch, pre-wired and complete with ¼" output jack. Follow simple instructions provided to wire transformer secondary to switch, mount switch and ¼" jack in separate 3/8" diameter holes in chassis and you'll easily be able to select output impedance as necessary. (Not recommended for 1645A or 1650G) (See P-H1600 for a selector switch to work with Hammond 1600 series transformers.)
