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.)

The PRC-1 audio choke from One Electron was designed for shunt-feed single-ended output applications, but is also useful where quality inductive loads are needed or as high-quality filter chokes.

The PRC-2 audio choke from One Electron was designed for shunt-feed single-ended output applications, but is also useful where quality inductive loads are needed or as high-quality filter chokes.

• Designed for general purpose or replacement use (not Hi-Fi), in single ended, tube output circuits.
• Frequency response: 100 Hz. - 15 Khz (± 1db max. - ref. 1 Khz). (For full frequency response (20 Hz. to 20 Khz.) - see P-T1627SE).
• For push-pull output use, see P-T125A - optimized for push-pull tube output circuits.
• Open style with minimum 12" long primary & secondary leads leads.
• All sizes use butt stacked cores (using 29M6 steel) with an air gap, to reduce D.C. core saturation.
• Primary impedance range from 2,500 to 10,000 Ohms.
• Secondary impedance range from 4 to 32 Ohms.
