For sale Adcom GFA-5500 in excellent working condition. Barely used. No Issue. No original box. NO SHIPPING. Local Pick Up Only in Hayward, California. Power output: - 200 Watts continuous average power into 8 ohms - 350 Watts continuous average power into 4 ohms Frequency response: 10Hz to 20kHz Total harmonic distortion: 0.02% Damping factor: 700 Gain: 29 dB Input sensitivity: 1.4V Signal to noise ratio: 100dB Dimensions: 178 x 432 x 349mm Weight: 25.9kg 57lb Completely Separate Secondary Main Power Systems. The GFA-5500 has a specially wound high power toroidal transformer which completely isolates the two channel secondary systems, not even sharing the ground connection. This eliminates ground loops and greatly reduces the possible interactions between power channels. High Capacitance Storage. Each channel has nearly 120 Joules of energy storage, adequate for 14 kilowatts of power at 10% ripple. Under normal operation, the power supply ripple voltage is less than 1%. Separate High Voltage Front End Supplies. The front end circuitry of each channel is supplied power by its own high voltage system - including separate transformer windings, bridge rectifiers and filter capacitors for each channel. This eliminates interaction between the early gain stages of the amplifier and the high power occurring in the output stages. The front end system is operated at a higher voltage than the output stage. This not only improves the distortion characteristic of the front end, but allows the front end to drive the output stage to its supply rails - obtaining every bit of available power to the load. In Rush Limiting. The power supplies feature inrush limiting which prevents the high current surges which would normally accompany the charge cycle of the transformer and the power supply capacitors on turn-on. CIRCUITRY 100% MOSFET Construction. All audio elements of the amplifier are Power Mosfets Even the input transistors are power devices, capable of as much as 2 amps of current by themselves. The transconductance characteristic of Mosfets have a number of advantages which are put to good use. Their high input impedance allow for the use of an extremely simple gain path, and their negative thermal characteristics give high thermal stability, allowing high output stage bias, low offset voltages, and very high output current and voltage with reliable operation. The characteristics of the Power Mosfets are sonically superior to the Bipolar transistor, delivering all of the muscle of Bipolar circuitry with the sweeter qualities found in tube equipment. Ultra Simple Gain Path. Most high end amplifiers have at least 5 successive gain stages associated with their signal path. Some have even more. The GFA-5500 achieves all of its performance with only three. Thats two stages less for the signal to travel through, and it makes a difference. Thank you for looking.
