We have one of those too. It looks just like the Powerflex 12 featured in Post #277628, except the dispenser is not as tall. Our washer was one of the last models that had a lid the size of the A712 above.
The sound is very different. It is the short fast stroke (approx. 160 opms per minute), and with the protruding fins up the agitator shaft, you can hear the rhythmic sloshing of the water on a full load. The first time I heard one of these run, I thought Maytag had adopted the Frigidaire method of vertical agitation; the rhythm, with the splashing bear a similar sound. Once I actually watched it, I knew this was not the case. It generates a fair amount of turnover, and does a nice job cleaning.

Congrats on getting that gorgeous A712! Back in 1985, that model was my dream machine. I remember seeing those on a showroom floor, and as I remember, it actually shined brighter than other models. I kid you not about this. These were in the stores for several years, and in my book, anyone who bought them was the luckiest person in the world.
Have a good one,
James
