ADCOM GFA-585 (Limited Edition)(Famous)( Near Mint Condition) THE PRIZE Here is another fine offering from the audio lab’s ofMorris Electronic Repair Boutique This ADCOM GFA-585 is a 555 II on STEROIDS! It’s the Mother Of All Power Amplifiers. The heat sinks are massive! This is a true very rare classic. Plus this is a Limited Edition with the numbered nameplate of 1570 on the front. This baby will not only light up your Wilson Audio Sophia Series 3 speakers, but will power any speaker in the world! At 250 W into 8 and 400 W into 4 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. It is a very HIGH CURRENT amp with a rail capacitance of 36 thousand uF per side, This 585 has a time delay circuitry to apply the rail voltage after all bias networks are up to speed, eliminating the speaker thump on turn on /off. I personally would put this 585 up against any of the big boys like Krell - McIntosh- Jeff Rowland- Classe Audio, etc. It will hold it’s own, if not easily surpass. If you want to save a bundle on this amp contact me using the blue letters on the last pictures BUT WAIT THERE’S MORE This particular GFA-585 is very special, it has been upgraded with two Brand New double sided audio driver board with all brand new audio grade 1% tolerance audio grade components.The soft start board has been upgraded with all brand new capacitors. The output modules have been upgraded with new higher performance capacitors. And the driver transistors, four in all have been upgraded to higher breakdown voltages for more headroom. Make no mistake this GFA-585 is not your Dad’s 585 It will surpass anything out there in the 585 world. It’s sonic sound stage is nothing short of Awesome. If you have quality speakers & pre-amp to run this, you will lack for nothing in incredible listening pleasure. I have installed a IEC connector and will come with a generic IEC power cord. 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 this GFA-585 Power Amp, (as you can see by the pictures) insuring everything is to factory specs. I have many exhausting man hours in the refurbishing of this amp. Because it is so special, I gave it extra care. I leave no stone unturned. This unit (after initial check out on a Sencore PA-81 analyzer) has undergone hours of testing under load, driven by a Carver TL-3200 music source, into a Harman Kardon 825 preamp and a pair of Paradigm Esprit B/P 8 ohm 300 w Towers. The following is the electrical specs: On the rail capacitors.C1: listed 18,000 uF Tested 19,300 uF. Allowed leakage 9,000 uA Tested 840 uAC2: listed 18,000 uF Tested 19,400 uF.

Allowed leakage 9,000 uA Tested 780 uAThe idle current (Drive bias) was adjusted to 23.5 mV per side The DC offset is .4 mV on the left and .3 mV on the right (super low)The ser.# of this unit is 047801570The Limited Edition nameplate is Ser # is 1570THD is .002% which is incredibly low! Plus at any frequency it is less than .02%This unit draws 1.1 amp at 115vac, at idle. As always I pack everything with the best of materials, so as to thwart the gorilla UPS handlers. It will arrive alive and unscathed. And you will appreciate the effort when it arrives undamaged. The service manual & owner manual will be included (reproduced from original) also my real E mail address will be on a cover letter, so if you have any issues I will fix them pronto, this is why I maintain a 100% feedback. Thank you, for reading all my verbiage. This is one Fantastic Powerhouse of an amplifier in Near Mint condition. Any issues you should have I take care of them, period! This is why I maintain a 100% positive response.I answer all submitted questions.
