Adcom GFP-565 preamp. One owner. Excellent working condition.Has been sitting in storage for the last 10 or so years and just now getting around to selling. Everything works perfect on this beautiful sounding pre-amp. Was a Stereophile favorite upon release and still performs beautifully today. For awesome two channel music at an affordable price this is a great sounding piece. Signature required for delivery.Thanks for looking.

I am selling my gently used Adcom GFP-565 preamp. I am the original owner and bought this new in 1992. I dont need all these inputs anymore since I have down-sized and all I am running on this system these days is a TV and CD player. It is in excellent condition and has been really well taken care of in my non-smoking home for all these years. 2 of the little rubber bumpers on the sides of the cabinet are missing and there is a broken screw on the bottom panel (from my cleaning it periodically over 30 years), but everything else is in good shape. I recently cleaned all of the switches & pots with Deoxit so everything works and sounds amazing. Comes with manual.

Pound for pound, dollar for dollar this vintage set of highly collectible Adcom Mono Block amplifiers give more performance and raw power, than most amps triple or more than their cost. Very rare and harder and harder to find, this Adcom Stereo GFA 565 Mono Block Amplifier set, 300 watts per channel into 8ohms, comes complete with Hoppe’s Brain driver board and capacitor upgrade and overhaul, correcting the eventual leaky capacitor problem. The amps come in original factory boxes, with instructions manual. Cosmetically rated 8 or 9 depending on how picky you are, very minor wear and working condition rated 10. Runs quietly and perfectly and presently easily driving a $20,000 pair of Carver Amazing Line Source Speakers. Shipping on 2 Amplifier boxes by UPS will be approximately $65 each, final shipping price will be determined and sent before final mailing. Items are in perfect working condition, Shipping fragile electronics can sometimes loosen wires etc., I will not be responsible for shipping damage, but all items will be fully insured and tracked with shipper, who more than likely will be UPS.

Amazing sounding “Top of the Line” Adcom GFP-565 preamplifier. Phono stage plays both moving magnet and moving coil phono cartridges. Preamp works flawlessly. I have been using an integrated amp and have not used this component for years. I plugged it into my current set up and ran it for several days.Everything works perfectly and it sounds wonderful. You will not be disappointed. It has always lived an easy life and looks great.

You are bidding on a PAIR of pre-owned Adcom GFA-565 mono-block power amplifiers. The sonic performance of these amplifiers is well-documented. Cosmetic condition of both units is good and reflects normal home use. Small tear in exterior power cord (outside casing - picture provided) but no exposed interior wires. Electrical tape was removed for photo. Both units were professionally serviced in 2018 to correct common leaking capacitor issues found in this model (receipt/verification of service to be provided with purchase). Both units were used in my home audio system for many years and sound great. Units will be shipped separately and securely to domestic U.S. buyers only. Free local pickup (if southeastern Virginia). Owners manual included. Additional pictures can be provided upon request. Good luck - happy bidding!

Stunning high performance reviews. Appears like new both functionally and cosmetically. Manual included Adcom Model GFP-565 Solid State High Performance Stereo Preamplifier - Mint Description Thank you for checking our listings. Please purchase with confidence.  Item:  Adcom Model GFP-565 Solid State High Performance Stereo Preamplifier Original retail price: $798 Estimated Production:  1990 Product Information The Adcom GFP-565 2-channel pre-amp/processor amplifier is designed to compete with any high-end pre-amps on the market. This unit offers a unique setup with three sets of outputs and loud, crisp surround performance for bypass, main outputs lab, and main normal that allow you to easily choose the voltage to provide to speakers and to control tones or, alternately, to enjoy an unfiltered bypass. They use a direct path, and linear gain circuitry within the device helps to further improve its sound purity and performance. In addition, there are six inputs provided on the GFP-565, including phono, CD, tuner, tape 1 and 2, and video/aux via cables. There are separate selector switches that are provided for listening and recording, and since two tape outputs are also included, tape copying in either direction is possible. The 565 does not have an infrasonic filter for the phono. The Acoma GFP-565 2-channel processor amplifier has extremely robust power amplifiers that are capable of operating at a very low impedance of 2 ohms and can manage difficult speaker loads thanks to its 20 rugged output transistors. It was designed around a triple Darlington configuration and uses no protection or current limiting circuitry other than the fuses itself in the DC supply voltage rails. This sound system could be considered monster speakers as they are very powerful, delivering a massive sound, yet have really balanced acoustics. They are rated at 300 watt output for 8 ohms (24.8 decibel watts), 450 watts into 4 ohms (23.5 decibel watts), 850 watts into 2 ohms (23.3 decibel watts), and all 20 hertz to 20 kilohertz at 0.02 percent. They have an impedance of 50,000 ohms and an input sensitivity of 2.15 volts for rated output. Their full output is greater than 106 decibels, their damping factor is greater than 1000, 8 ohms, 20 hertz to 20 kilohertz, and they have a dynamic headroom (at 4 ohms) of 1.6 decibels. The bypass outputs will let you use an external processing loop, and a mono switch and loudness contour help your sound bypass outputs, but the contour switch and its associated filter components are connected to a tap on the volume control, so these components and switch contacts are not in the signal path. Designed as a solid-state monoblock power system, it uses one very large, beer-can-sized capacitor. It also consists of a high-quality, X2-type snubber capacitor, which is installed across the AC input to reduce RF interference and reduce noise. This amp, even when driven hard and heated up close to maximum, shows no signs of distress. It should cool itself down quickly too. ADCOM made its name in the boom-box days of the ’80s with this type of speaker, offering a truly high-performance audio system for the mass market. They were leaders in developing semiconductor technology, which was accelerating along with fabrication technology. But it’s not just about volume. This sound system will please the purist audiophiles as well as all those who require the abilities of full-featured speakers, such as electric guitarists. The ADCOM GFP-565 2-channel audio system will offer years of quality use in its clean, solid, and secure system.
