Audio-Technica AT630 Moving-Coil STEP UP TRANSFORMER Good WORKING Condition, SUT - $100 - (Colville, WA)

This listing is for a used Audio-Technica AT630 step-up transformer. It is designed to boost the output from a low-output moving-coil phono cartridge (NO cartridge is included here), so that it can be connected to a standard moving-magnet phono input. It is in good cosmetic condition, with only some light marks on the exterior, most of which are tiny specks of missing paint. It has been tested and works great. The Audio-Technica AT630 is a compact, cylindrical design, measuring approximately 4 1/2" long by 1 1/2" high. To use the AT630, you connect the output cables from your turntable with a moving-coil cartridge, to the pair of gold-plated RCA input jacks and grounding post on one end of the cylinder. The other end of the AT630 has a hardwired cable approximately 16" long with gold-plated RCA plugs and a ground wire that are then connected to the moving-magnet phono input jacks and grounding post on your receiver/preamp. The AT630 provides about 20dB of gain, which is sufficient to boost the output of the vast majority of low-output moving-coil phono cartridges. Step-up transformers, like the Audio-Technica AT630, have the advantage over traditional signal-boosting pre-preamps or "head amps" in that they are "passive" devices which are much less likely to introduce background noise into the boosted signal from the moving-coil cartridge. As shown on the exterior of the AT630 itself, it "Matches Moving Coil Cartridges rated at less than or equal to 20 ohms to 47Kohm magnetic phono inputs".Here are some additional specifications on the Audio-Technica AT630: Input impedance: 20 ohms or less Output impedance: 47 kohms Gain: 20 dB Frequency response: 15 Hz - 100 kHz THD: 0.05%, 15 - 100000 Hz Dimensions: 46 x 119 mm Weight: 37.5 g Please take a close look at the pictures attached to this auction.
