Wow!  What a big microwave you have... LOL

 

Congratulations on saving this one!  I'm guessing it's a Tappan.  
 
So glad this went to a good home, Anthony!! I'd never seen one like this before...couldn't believe how heavy it was...hope you can get it going again!

If I remember right they operate from 900 Mhz to 1 Ghz. Almost all had a 900 watt magnetron in the 50's I think that the 60's MW's were the same.  
 
Early MWOs

All these MWOs in question operate at 2450 Mhz just like current MWOs, the odd ones were GEs full sized ovens that combined microwave cooking in regular P-7 self cleaning ovens, these all operated at 915 Mhz.  GE built these 915Mhz ranges from 1966-1975 and then they switched to 2450 Mhz for the remainder of the time that GE made any combination ovens.

 

I have had 9 of these GE 915 Mhz combination ranges and still have 5 of them, I have heard that GE built some of these MWOs earlier than 1966 but can not find any evidence of them selling them to the public, I even though that this HP MWO cooking center was just a promotional appliance till Jeff [ MoparVrigina ] spotted this one in York Pa a few months ago.

 

I purchased the HPCC from a guy that bought the house where the HP had been delivered to and used in 1958, he gave me all the orignal paperwork and cook-books etc with it.

you are right.

 

it was shown by Kinn and Marcum (1947) that various sizes and shapes of heating cavities could be obtained by varying the wave guide termination. Similarly, the effect of heating and thawing foods with microwaves was studied by Morse and Rivercomb (1947) at 1,050 megacycles. They first described the "runaway" problem wherein the food thawed at one point and attracted a disproportionate share of energy.

In the early efforts, the Raytheon Company, the General Electric Company, and the Westinghouse Company were actively pursuing development programs in the United States. Raytheon selected 2,450 megacycles as a frequency for concentration while General Electric preferred to work with a frequency of about 915 megacycles. The U. S. Navy hoped to find a more appropriate method for preparing food in submarines and sponsored evaluations of ovens through the Bureau of Medicine and Surgery (Sussman 1947). They remained optimistic but respectful of the skills and special equipment involved.

That is so awesome you got all the info with it too!

Well

I think I finally figured out why none of these 50's and 60's MWO's won't work. If the nutrel line is tied to ground it back feeds high voltage simi DC thus shorting out the transfers then blowing the fueses. I tested this Thierry with the 1957 and this 1962 and its spot on. About 4 seconds and bam blown fueses! Un hook the "ground" works perfectly! So with that being said the 62 now works just whating on a pump that I can make work and it will work. John call me when you have time.
 


Me too Kevin! Btw that's a really nice stove you put in! Here are some pics of replaced parts/improvised parts. The pump could not be saved so I used a small 12V pound pump. I was trying to find a small 120V pump but as you can see that didn't happen. I will have to try cooking something that takes a long time and see if this little pump will have enough flow to keep everything cool.

I can't eat White Castles.

You wouldn't want to be near me if I did.
But I have had turkey stuffing made with them, and maybe it was the added broth, stock, and the juices from roasting inside the bird, but it didn't have the same effect.
It was also delicious. Once a year won't hurt anyone either.
 


I love the White Castles but I think the best is Bates Berger's! I can't believe that old man bates is still alive he must be 99 now.
 


It's at like 9 mi and grand river. I haven't been there in a long time but I guy I work with lives close and stops for me time to time. I will look it up for you.
