I have an excellent condition Proton AA 1150 stereo power amp for sale. It is a dual mono construction with seperate transformers , caps, output devices etc. in one chassis . It features Protons' dynamic power on demand with a full 7 db. of headroom so it can put out in excess of 200 watts when needed. It was serviced recently and had the meter lamps replaced was cleaned and had some solder joints redone with high strength antimony solder for reliability. It is a beatiful amplifier with a glass front and two large green lighted VU meters and a green illuminated power switch . Amplifier is high current and 2 ohm stable. Works perfectly and looks great. I would like $150.00 shipped to lower 48 states. I prefer Paypal or money order. Email me at [email protected] if interested.
