I have a STA-80 receiver hooked into my stereo.
I just use it for AM/FM. It is one of the most sensitive receivers I ever listened to.
Pretty sad, some of the sta-xxxx stereos were some of the best of their era. I had a Sta-350 laboratory standard. Incredible sound and efficient 50 watts drove a room of speakers. I’m still running some Op-9 speakers (5 way) from 1972. These are great looking speakers even after all these years. I worked there in the late 70’s. It was hard to convince customers the stereos were competitive. We mostly sold cb’s. Kitter’s were big then, even during the chip era. There was some great books on chips and breadboard experimentation. No one wants to be a electronic hobbyist now. I wonder even if there are any audiophiles left in this era.
