Original Description:
EICO HF-14 14 Watt Hi Fidelity Power Amplifier
This auction includes one Eico HF-14 Watt Hi Fidelity Power Amplifier.  Please take a look at my other Eico HF-14 amp auction, as this amp was originally paired with another at the General Motors Corporation Electronics Division.  This amp has the longer power cord of the two.  Untested but all connections look good.  DescriptionThe Eico HF-14 is a 14 watt high fidelity basic power amplifier employing two E...L84 output tubes (not included) in push-pull and a high quality output transformer. The high power sensitivity of these remarkably fine tubes eliminates the necessity for additional driver stages, permitting the use of a large amount of inverse feedback with a high stability margin.The lower operating voltages required and the use of EZ81 rectifier tube having a warm-up characteristic exactly matched to the output tubes, result in a power supply of exceptional reliability as well as extended output tube life. Filter electrolytics and the rectifier operate well below maximum ratings and voltage surges at starting are eliminated.The HF-14 has been designed to maintain its excellent characteristics under speaker load (including electrostatic types) as well as the resistive toad normally used for testing. Phase corrections have been provided at both extremes of the audio spectrum to insure stability under all conceivable conditions and to insure that variations in components and construction will not affect the performance.Stability is maintained on all speaker taps with loads ranging from zero to infinity. Overload characteristics are excellent and the HF-14 will not exhibit bounce or flutter under pulsed conditions. It can be operated from any preamplifier control unit.A power take-off socket is provided for powering the Eico HF-65A and HF-61A pre-amplifier control. Other features include a panel mount fuse holder, switched and unswitched convenience outlets, and heavy gauge cadmium plated steel chassis finished in baked enamel.Specifications Power output: 14W into 8Ω (mono)Frequency response: 20Hz to 20kHzTotal harmonic distortion: 2%Damping factor: 8Input sensitivity: 1.25VSignal to noise ratio: 90dBSpeaker load impedance: 4Ω to 16ΩValve complement: 1 x ECC83, 2 x EL84, 1 x EZ81Dimensions: 3.75 x 12 x 4 inchesWeight: 10lbs(These Are Factory specifications and were not tested on this specific unit)
