Mixer Design and Julia's Comments
The Mixmaster model 9 was a wedding gift Julia received. The beater with the bowl speed button was not in the correct position. This one is the early in the manufacturing run having the older decal on the mixer motor. (Same as what was used on models 5 and 7) Julia describes in detail in her cookbooks, proper egg beating equipment.
During the 1970s, Julia also had a cooking column in McCalls magazine. She tested the Power-Plus mixer and describes in detail the evaluation in one installment of her monthly column. One has to wonder if Sunbeam sent the mixer to her seeking endorsement or inclusion of the mixer in her show. She had quite a following building when launching a second series of cooking shows on PBS. The Power-Plus mixer had deeper, narrower bowls, much larger beaters & dough hooks and much larger, more powerful motor. The design flaw of the mixer was the electronic speed control, it could not tolerate running for long periods under a heavy load. The mixer was Sunbeam's attempt to compete with KitchenAid. The mixer had citrus juicer, food chopper, and slicer/shredder attachments.
The Kenmore Ovation stand mixer has the same flaw because the mixer beaters only "covers" half the bowl.
