Fidelity Research FR-14 Tonearm in excellent cosmetic and working condition. Cable and headshell included. While incorporating many of the innovations of the FR-66S and FR-66, the FR 14 arm features an unusual design approach in which the arm pipe is offset from the pivot point to allow a shorter pipe to be used. This is an advantage since effective mass is lower, yet the pipe itself is stronger and does not need as large a curve as in conventional designs. The headshell connector is a proven, highly reliable design. The anti-skating device can be adjusted to begin operation at the point considered optimum The FR14 is a statically balanced tonearm and the counterweight is easily and accurately adjustable by means of a precision rack and pinion device built into the weight.

International shipping possible. Please ask for shipping costs. Heavy weight 2x35 kg! Audio Research V140 Mono Tube Amps The V series power amplifiers represent an evolutionary refinement of the circuit topology first established in the acclaimed Classic amplifiers introduced by Audio Research a few years ago. While continuing to use triode operation and Audio Research's patented, cross-coupled circuit, the V amplifiers also incorporate a fully balanced input stage to minimize noise and distortion products that otherwise could degrade the musical resolution of the output stage. The input stage uses select J-FET transistors with MOSFET followers to provide ultra-quiet, low-impedance drive to the 6FQ7 dual triodes, which directly drive the output tubes. (The V amplifiers are shipped with matched, selected KT90 output tubes, although other popular alternative tube types are compatible: 6550. 6550A. KT88 or KT100.) 120 watts minimum continuous at 4-16 ohms from 20Hz to 20kHz with less than 1.0% total harmonic distortion (typically below .005% at 1 watt). Approximate actual power available at clipping: 125 watts (1kHz) (Note that the actual RMS power output is dependent upon both line voltage and condition ie: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)

ATTENTION! This auction is for AUDIO RESEARCH PREAMPLIFIER SP 14 ONLY!!!!! If you want to by extra AUDIO RESEARCH CLASSIC 60 - See My other auctions. The SP14s musicality comes surprisingly close to the state of the art, with soundstage of remarkable depth and breadth; imaging of uncanny solidity: palpable dynamic authority; timbral accuracy that virtually recreates live music; an exceptionally low noise floor; and a special ease with frequency extremes. But unlike many high-performance preamplifiers, the SP14 doesnt scrimp on control features. It has separate Gain and Attenuation for wide-ranging-yet-subtle level management. Separate Input and Record Output selectors (with a common menu) permit exceptional flexibility in playing and recording: owners can listen to one source while recording from another. The Bypass switch allows owners to remove the Balance and Mode controls from the signal path, for greater sonic purity. There are two separate sets of outputs, and three power outlets. And, of course, the SP14 features its own version of the hybrid technology that has made Audio Research electronics world-famous. As with every Audio Research product, SP14 parts quality, construction and factory support are the finest in the audio industry, with a two-decade track record to prove it. And all this comes at only half the cost of the celebrated SP15. FREQUENCY RESPONSEHigh-level section: ±.5dB, 5Hz to 50kHz, -3db points below 1Hz and above 200 kHz.

ATTENTION! This auction is for AUDIO RESEARCH AMPLIFIER CLASSIC 60 ONLY!!!!! If you want to by extra AUDIO RESEARCH PREAMPLIFIER SP-14 - See My other auctions.The new Classic 60 Hybrid Stereo Power Amplifier resembles the long-popular D115 in Audio Researchs family of High Definition® power amplifiers. But its lineage is strictly Classic 150. Which means nothing less than state-of-the-art in design, construction, musicality, and operational convenience...at an affordable price. Like the Classic 150, the Classic 60 proceeds from the notion that power ratings dont always describe a power amplifiers real capabilities. Far more important are such qualities as dynamic stability. lucidity, subtlety. And to achieve those, Audio Research has used its traditional partial cathode coupling along with triode operation of the Classic 60s eight 6550 power output tubes. Additional circuit improvements, as well as the usual rigorous parts selection and manufacturing Audio Research, are noted for, also contributing sonically. Translated into the language of listening, this signifies stunning bandwidth, a noise floor virtually beneath audibility, and musically fulfilling SPLs at dramatically lower gain settings. Dynamics, timbres of individual instruments, soundstage, and musical emotion all surge out from a black velvet of silence. Simply put the Classic 60 resolves far more of a musical program than amplifiers rated at two, three, or four times its seemingly modest 60 WPC. But the Classic 60 is easily up to the task of driving all but the most demanding loudspeakers, even in spacious listening rooms. And while it shows modest preamplifiers in their best light, it also shines when coupled with premiere designs, such as Audio Researchs SP14 or SP15. Convenience figures are high on the Classic 60s list of attributes, as well. For example, the DC balance of the output tubes is maintained automatically, while tube biasing continuously adjusts to changes in incoming line voltage. Performance stays razor-sharp without bothersome tweaking or adjustments. And quiet fan cooling, along with triode operation, means significantly longer tube life.

(1kHz) (Note that the actual RMS power output is dependent upon both line voltage and condition ie: if the power line has high distortion, maximum power will be affected adversely, although, from a listening standpoint, this is not very critical.)POWER BANDWIDTH(-3dB points): 12Hz to 40kHzFREQUENCY RESPONSE-INPUT SENSITIVITY.55V RMS for rated outputINPUT IMPEDANCE100K ohms, nominalOUTPUT TAPS-OUTPUT REGULATIONApproximately 0.3dB 16-ohm load to open circuitOVERALL NEGATIVE FEEDBACK20dBDAMPING FACTORApproximately 30DISTORTION-SLEW RATE20V/µsRISE TIME2.0 µsHUM & NOISELess than 2.0mV RMS - 84dB below-rated output (20kHz bandwidth unweighted, inputs shorted)POWER SUPPLY ENERGY STORAGEApproximately 280 joulesPOWER REQUIREMENTS105-125VAC 60Hz (210-250VAC 50Hz) 500 watts at rated output, 700 watts maximum, 370 watts at idleTUBE COMPLEMENT(4 matched pairs) 6550 power output, (4) 6FQ7/6CG7 driversDIMENSIONS19 (48 cm) W (standard rack panel) x 7 (18 cm) H x 15 ¾ (40 cm) D (front panel back).
