One Thing to Remember:
As wonderful as 906s were and are, the first-series A806 is exactly the same machine from the console down - and much more plentiful.
I would venture to say this is because prospective purchasers looking at the brochure or machines on the sales floor could easily see that the 906 was automatic as all Hell, but what it was not was versatile.
This was in stark contrast to the Lady Kenmores of that era, with their three speeds, their double row of pushbuttons for cycles and a timer dial that allowed you to play and play and play with cycle modifications.
So, if you had any desire whatever to be in charge of what happened to your clothes, and you wanted a Maytag, the A806 was the natural choice.
I personally consider both the A906 and the A806 top-of-the-line machines. One was a TOL pre-programmed machine, the other a TOL user-variable machine.
P.S.: The survival rate for A806s seems to be much higher than for the Lady K competition; less mechanical complexity appears to have paid off for the Maytag machines.
