The power amplifier seems to be in great condition. Ill front lights light up. It is untested but it did not hear any bad sounds coming from it when I plugged it in. Not knowing enough about the item I do not know what would happen if I plug speakers up to it. Im lowering it sell price just because I didnt know if it works or not. I mean it plugs up just fine but Im not sure of functionality. There was also no electrical smell whwn plugged in.

I’ve had this amplifier for many years. I was friends with the original owner who bought it new in the late 1980s and I’ve use this every couple years to spin some albums and now I’ve decided to sell it. I have original boxes for all three components. These will ship in the original boxes and will have an outer box as well to protect the original box. This is an extremely rare set up and yes, the shipping will be a little pricey, but well worth it. Please see my auctions for the other components.

Proton AA-1150 power amp Black Large illuminated meters Great overall condition 50 watts per channel into 8 ohms Never been opened Amazing amp outstanding clarity, depth, balance

*UPDATE* I realized from viewing my own advert that my pictures weren’t really representative of how bad the case of this amplifier looked. I didn’t want the buyer of this amp to be disappointed by this and so I removed it and gave it a refresh of flat black primer and paint. The last 4 pictures are new and will give you a better idea of what it looks like. I’ve personally owned this amplifier for 30 years. It has been used off and on again in rotation and has always worked flawlessly. The chassis is not perfect but the front glass is clean. I’ve never had to have this repaired. Its sound is astonishing when compared to other amps and receivers from the same era. They have all come and gone and this has stayed with me. I’ve owned so so so many amps, and this wiped the floor with a good many of them. Here’s some extra generic info I pulled from someone else’s advert. A rare, high-quality vintage amplifier! Don’t be fooled by the 50wpc rating. Proton’s Dynamic Power on Demand gives it a claimed 7dB of headroom which, as Julian Hirsch said in his June 1988 review, makes it, “quite possibly the world’s most powerful “50W amplifier””. It’s a dual mono design and offers exemplary performance and musicality. Notably, Julian Hirsch found that it exceeded almost all of its published specs (shown below). Manufacturer’s published specifications: Rated power output: (20hz-20khz into 8ohms) 50w per channel Dynamic power: (at 8ohm/4ohm/2ohm) 280w/450w/600w IHF standard 20ms duration 100ms duration 220w/300w/350w Dynamic Headroom: (at 8ohm/4ohm/2ohm) 7db THD at rated power 0.02% Dimensions: 16.5” W x 14.5” D x 4.25” H Weight 25 lbs

Used amp, in working condition but certainly needs a tune-up and a good cleaning.I dont use it anymore, owned it for about 30 years now, currently dont need it. Its priced for someone to recondition and love or resell. IT IS NOT MINT but it 100% works.Right channel drops out at low volume, but I think thats dirty RCAs. Unit is currently boxed and ready to ship out.
