ADCOM GFA-565 Mono block (Power House Amplifiers) (Famous) (matched pair) If you want to save money on these contact me using the blue letters on the last picture Beautiful condition, Better Than New Inside THE AUDIO PRIZE AWAITS YOU Here is another fine offering from the audio labs of Morris Electronic Repair Boutique This pair of ADCOM GFA-565 Monoblock’s are in beautiful condition, (near mint) which have been completely refurbished. These are a very rare classic. At 350 Watts / 8 These baby’s will not only light up your Wilson Audio Sophia Series 3, but will power any speaker in the world! At 450 Watts /4 or 850 Watts / 2 continuous, it will handle the most demanding loads. The clarity, musical definition and sound stage will literally speaking “ blow you away”!! You are not going to find many of these around, for the lucky people that own them keep them! The design and power is second to none. These are very HIGH CURRENT amplifiers, with a combined rail capacitance of 70.000 uf per unit, which gives lots of head room. These 565s have a time delay circuitry (soft start) to apply the bias voltage after all the amplification circuits are up to speed, eliminating the speaker thump on power up, and also to protect your speakers in case of circuit issues. I personally would put these 565s up against any of the big boys like Krell - McIntosh - Jeff Rowland - Classe Audio, PS Audio etc. It will hold it’s own, if not easily surpass. These two amplifiers are the pinnacle of audiophile euphoria. Both of these amplifiers are EXACTLY! The same! Except for serial numbers BUT WAIT THERE’S MORE SOMETHING NEW: There is a BIG DIFFERENCE with this pair of 565s, from the originals. The driver PCB’s are brand new double layered PC boards. ALL the components on the driver PCB’s are brand new, 1% audio grade components from US mfg. Vishay, kemet etc. (very expensive) The driver heat sinks are enlarged from original to dissipate the heat more effectively. Everything on the PCB’s have been upgraded to the highest audio grade component’s to give the best low noise sound reproduction possible. Plus expect to get a minimum of 30 years service from these refurbished amplifiers, before any degradation of components. And even then it would be negligible. I am a one man shop, with 30 years as a electronic tech, so each piece of high quality audio equipment gets my personal attention, of which I repair, clean, adjust, and inspect everything as if I were keeping for my own. I have personally been completely through the internals of these GFA-565s (as you can see by the pictures) insuring everything is to factory specs. I have many exhausting man hours in the refurbishing of these amplifiers and with populating the new driver PCB’s with all brand new components. Because these were so special, I gave them extra care. I leave no stone unturned. So you can buy with confidence knowing you are going to receive two very high quality amplifier’s in perfect condition electronically and beautiful condition cosmetically.. These unit’s have undergone hours of testing and burn in under load, driven by a Harman Kardon CD 491 player into a Harmon Kardon 825 preamp into Paradigm B/P Espirit 300 w Towers. The externals are in better than new condition. The driver boards are new with all new audio grade 1% tolerant components. The bias voltage was adjusted to 23.5 mV per unit.The two electrolytic are new on the output modules and have been upgraded to 100 uF/160 v with .1 400 v mica’s in parallel. All the caps on the soft start board are new. The rail capacitors of 35,000 uF have checked out to be 42,200 uF & 40,700 uF on amp 1The rail capacitors of 35,000 uF have checked out to be 46.900 uF & 42,800 uF on amp 2The rail capacitors allowed leakage of 9,000 uA checked to be 460 uA & 430 uA amp 1The rail capacitors allowed leakage of 9,000 uA checked to be 610 uA & 530 uA amp 2 The S/N # of each unit is 019215914 & 007213339 THD is .002% which is incredibly low! Plus at any frequency it is less than .02%The DC offset voltage at the speaker terminals is .1mV on amp 1 & .3 mV on amp 2These units draw .9 amp’s at 115vac per unit at idle. Blem list: On only one amp, on the top there was a couple of very small rust spot’s which I have touched up. They are hardly noticeable. Other than that these amp’s are in near mint condition. Please Note: I only ship in the US. No international shipping! As always I pack everything with the best of materials, so as to thwart the gorilla UPS handlers. It will arrive alive and unscathed. The service manual & owner manual will be included (reproduced from original) along with amplifier spec sheets on each amp after testing. And will carry a one year iron clad warranty against all parts & labor and I will pay the shipping both ways in the unlikely event an issue should occur. Thank you, for reading all the verbiage, for these are the (cream of the crop)!! Fantastic Powerhouse Amplifier’s in very Beautiful condition. Any issues you should have I take care of them, Pronto, Period! “ No If’s, And’s or But’s”. This is why I maintain a 100% positive feedback. I answer all submitted questions.
