The original tray was just a flat tempered glass shelf, all RR2s came with some type of glass shelf or molded tray. I have never seen an RR-1, but I would bet they also used a flat glass shelf,  would love to see one in person.

John, I'm wondering if the flat tempered glass could be reproduced? 

Hi Phil, it would be possible to have a piece of glass cut that would look much like the original tray although it might not be tempered glass, ours also has some strips of tape like material on both sides to make it easier to handle and I guess to keep it from scratching the SS oven interior. If the flat tray that I have didn't have the Amana label on it warning not to use the MW without the tray in place I would almost think that someone made this flat tray themselves. I suspect that a lot of these original flat trays got replaced with the later molded trays which fit perfectly in the RR-2s.

Hi Cory, actually the warning label is just a red sticker applied to the front of the tray.

MW corn popping and broken glass cooking trays.

This still happens in brand new MWOs all the time and it can happen the frist time you do it. When I use MWPC [ which I seldom ever do ] I always place a piece of Corning-ware in the MWO and place the PC bag on top of the CW. I would do this especially if you have a vintage MWO, something else to consider is whether your MWO is vintage or new, popping pop corn in any MWO is very hard on the magnetron tube and often causes early and dramatic failures of the mag tube.

John, if you have the chance to get the dimensions and thickness of the glass plate in your RR-2, I'd try to have one made to that size.

Congratulations! Does yours have the flat glass tray? If it does, I'd like to have the dimensions!

Thanks

I'd like if you could send a picture of it with the door open and if you have a chance to note or take another picture showing the serial number of your oven, it would be great! It's probably on a tag under it near the door

Here's a picture of mine:

Yes the later molded tray was diffidently an improvement, it was not only easier to handle but it contained pretty good sized spills.

Thanks for the picture!

The serial number if located between the door and the front leg on the early RR-2 models. It's easy to see if you move the microwave a bit on the counter as I did to take the picture...

Your glass tray doesn't seem to be clear. Is it textured? If I remember well, John's glass tray is clear?

Also, is there a buzzer on-off switch under the control panel? My RR-2 lacks a buzzer and a switch and I think John and Cory's RR-2 microwaves also lack them but some do have one like Jon's RR-2.

And you'll also hear the cooking through the door!
