Transformers & Chokes

Switch - Rotary Impedance Selector, for Hammond 1600A series
Includes: 3 pole, 3 position rotary switch (3P3T), 1/4" 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 1/4" output jack. Follow simple instructions provided to wire transformer secondary to switch, mount switch and 1/4" 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.)
