I have just acquired this unit (April 2017) and have connected to a set of three-way Klipsch Chorus II speakers. I am well impressed with this little guys output. Punchy base and crisp mid and high ranges. This is a 40 year old unit and is pushing out great sound. First impressions, if I had four hands it would be 4 thumbs up.

Found this little gem at a yardsale. Paid a small amount, and thought this could only surprice me in a positive way i had nothing to Loose.
And i did surprice me and in a Big Way! Only rated at 40 watt but what a Sound this little thing has. Rich and full and the Phono stage is great! Sounding. If you find one, just buy it, it Will surprice you.
