Nice. My first receiver was a Realistic STA-76 that I put on layaway as a young teen (14 ish?) with $100 that I worked like a dog for cutting lawns one summer. I tried to pay it off but never could. I think it was on sale for $219 marked down from $299. My sainted mother felt sorry for me and in the fall she paid the rest and I got it off layaway. I still have it in my office. It's only 12 WPC but it has the legendary Quatravox that is basically a Hafler circuit for ambient sound out of the rear speakers since Quadraphonic was all the rage when that receiver was built. A lot of the Realistic stuff back then was manufactured by Foster, and they were pretty darn good. Expensive, but the quality was very decent.
I remember in College, we all thought Watts Per Channel was the holy grail. We bought as many watts as we could afford, and they were expensive, but back then we (mostly) played Rock as close to concert levels as we could unless we were playing Jazz, then it was just Jazz Club levels on volume. I think I paid $400 for my Yamaha CA-810 (65 WPC) back then, and that was a CLOSEOUT price. That's almost $1,300 in today's dollars. But the way they were made, the WPC rating was ultra conservative. I drive that Yamaha into 4 ohms not 8, and it pushes close to 80 WPC at that level of impedance - probably like 78.5 wpc if you are getting technical. My school was a business and engineering school so half the guys were chasing an MBA and the other half were on their way to a Masters in Electrical Engineering. We'd sit for hours in the dorm quad and debate WPC, Sony VS Yamaha VS McIntosh VS Pioneer VS WHOEVER. We'd argue about Slue Rate and Class A vs B VS AB VS C and anything else you can think of. Those were the days!
Now, I just like quality and good tonality from amps and receivers, combined with legendary good looks and don't worry about WPC. My Realistic SA-1001 in my patio is rated at 35 WPC into 8 ohms. Again I drive it into 4 ohms so probably squeezing out close to 40 watts or so. And it sounds magnificent. I finally splurged for McIntosh a while ago and I love it. But you really don't need all that mega-power to be a happy audiophile. My opinion of course.
