The unit fundamentally works, in that it plays audio, but the sound quality is somewhat distorted. A recap service is likely needed to have this unit perform as it should. I will ship UPS Ground or USPS Priority, no later than 1 business day handling time (business days are M-F). This will be packed with exquisite care. I will accept returns within 30 days, but please carefully review the notes and all pictures before buying! Please also feel free to message me if you have any questions. Thanks for looking, and happy bidding!

This is for a top plate only in very nice Condition

FOR SALE: One pair of used Adcom GFA-565 mono-block power amplifiers (2 units). Both amplifiers were professionally serviced in 2018 to repair damage caused by leaking capacitors (a common problem for this particular model). These amplifiers were the second of two pairs used in my home stereo and theater systems for many years (hence numbers 3 and 4 in the photos; units 1 and 2 were sold earlier in 2023 via eBay). Serial numbers are 014215063 (Amplifier #3) and 951211927 (Amplifier #4). These units will only be sold as a pair. Both amplifiers are fully functional, sound wonderful, and are being offered for sale as-is. Please read my specific comments and descriptions of the subject amplifiers below. If you have any additional questions, please feel free to contact me. Thank you for your consideration...good luck and happy bidding!!! Appearance: Cosmetically, both units have blemishes and scratches (normal wear and tear) due to frequent use and movement in/out of various home stereo and theater configurations over the years, but are considered above-average (7 to 7.5 out of 10) for their age. I will send additional close-up photos of both units upon request. Sound and Performance: I have used these amplifiers with a pair of NHT 2.9 tower loud speakers. Sonically, both amplifiers sound excellent and have performed very well since being professionally serviced in 2018. Please note Amplifier #4 does make (actually the speaker connected to Amplifier #4 emits) a momentary static pop when that unit is initially powered on (the noise/sound Im trying to describe is audibly louder than when powering on Amplifier #3 or a similar high-current power amplifier), which could indicate an issue with the main power switch or circuit. I have not sought professional service for this unit, as it does not affect the audio performance of Amplifier #4 once powered on and in use (nor am I a professional qualified to diagnose what the actual cause of this might be). Specifications: A photo of amplifier specifications is attached, and a copy of the original owners and service manuals will be provided to the winning bidder. These are solid-state mono-block power amplifiers. Rated power output: 300W into 8 ohms (24.8dBW); 450W into 4 ohms (23.5dBW); 850W into 2ohms (23.3dBW), all 20Hz–20kHz at 0.02% THD. Frequency response: unspecified. Input impedance: 50k ohms. Input sensitivity: 2.15V for rated output. S/N (A-weighted, full output): greater than 106dB. Damping factor: >1000, 8 ohms, 20Hz–20kHz. Dynamic headroom (at 4 ohms): 1.6dB. Dimensions: 17.0 wide by 8.25 high by 11.50 deep. Stated weight is 41 pounds (per amplifier). Shipping weight is estimated at 45 pounds (+/-) per amplifier. Shipping: Both amplifiers will be packed and shipped separately and securely using new boxes and packing materials (as I do not have the original boxes). Buyer-paid shipping costs are $100.00 per amplifier ($200.00 total). Free local pickup is available upon request.

Up for sale is a complete set of Adcom GFA-565 amplifiers and GFP-565 pre-amplifier. They come in the orignal boxes along with a manual for each unit and an Adcom pamphlet style advertisement featuring the unit. The amplifiers are untested, as I do not have any speakers of compatible wattage. They both power on. The pre-amp is in working condition as far as I can tell, and I have been using it with my record player without issue. I am not an expert in high fidelity audio equipment and cant certify the performance of these units. They are sold as is, so please consider that these may need servicing to meet your expectations and ask any questions you have before bidding.

I am not a reseller. I have owned this pair of Adcom GFA-565s for over 20 years. I am the second owner. I had the capacitor service done on both amps. Both work great. They are in excellent condition. I have used them to power a pair of Dahlquist DQ10s. They are great for power hungry speakers - 300 watts each. Selling as a pair. Sequential serial numbers: 007213721 and 007213722. I have and will ship the original boxes, but will rebox due to the age of boxes.
