I have a catalog of home and apartment repair parts that lists a few replacement burners that have two elements in the burner. The listings for these say for GE through 1975. |

I'm not sure exactly when it was made, but I'd guess around 1960. -- Mark Lloyd http://notstupid.laughingsquid.com "Unlike biological evolution.

This is illustrated by them in their "chocolate test" where they melt a bar of chocolate on the lowest setting of their burner vs that of a competitor. The competitors seized the chocolate because it was pulsing at 3500 Watts while the Luxine did not because it was pulsing at 700 W. I think Viking markets Luxine induction units so that might be a place to research this. The above is found buried in the text of this article: http://www.appliancedesign.com/CDA/A...0VgnVCM100000f 932a8c0____ I do not know it this applies to all units or the specific model in the article. The OP might want to call Viking. Roland |

GE and Hotpoint ranges of the 50s and 60s typically had dual coil surface units with five switched heat levels: High -- 240V across both coils in parallel Second -- 240V across one coil Third -- 240V across both coils in series Low -- 120V across one coil Warm -- 120V across both coils in series The "infinite level" time regulated controls in modern ranges require much less wiring than the old style (less cost) and provide more user control. |

I grew up in a house built in the early 1970s that had a four burner
General Electric cooktop with a push button control mounted on the wall behind it. Each burner had eight or so buttons to regulate its heat output. When I visited last Thanksgiving, it was still in service.

"Peter A" > wrote in message ... -snip- > Microwave ovens work the same way, although I have some vague > recollection that some fancy models have variable power. I recently purchased a new microwave that has variable output power (labeled as "inverter technology"). It was sub $100 US so I wouldn't call it "fancy". It has 4 power ranges and uses duty cycle control between the power ranges to regulate the 10 available power settings. It is FAR superior at the lower power settings. When defrosting or cooking on low, my old microwave would singe and pause repeatedly. Cycling 1/4 power more often yields MUCH better results. The new microwave also behaves much better on my small backup generator - conventional microwaves have really poor power factor AND significant even order harmonics, both not appreciated by generator voltage regulators. The even order harmonics are from the voltage doubler magnetron circuit. On one half of the line waveform, the diode charges the cap up. On the other half cycle, it fires the magnetron with the cap in series with the line voltage. Since the back EMF when charging the cap is not equal to the fire voltage of the magnetron minus the cap charge, the waveform is highly asymmetrical. |
