i acquired it used in 1975. AR2ax speakers powered by an AR integrated amp. Not sure if it had a model number, but I recall it was around 50 watts/channel. It looked like the image below

Source was an AR belt drive with a Shure M91ED. I remember it had a gray plastic box for a head shell.

I really wish i still had that system. I still remember listening to Queen's first album to christen it. Being new to the hifi world at the time, it absolutely blew me away.
