So at an estate sale today we found this odd duck. It's a beautiful RR-2 style Amana Radarange. But, keep reading...
An Odd Amana Radarange Find...

and it has the glass shelf for a tray, but...
No buzzer switch and the model tag...
And the Plug, yes it's a 220 volt / 50 cycle machine! We wonder where this plug is from? Would it be safe to use on 220 volt / 60 cycle / 20amp outlet?
Anyone have any insight into this machine?

Radarange plug..
Its an Aussie/ New Zealand 240v plug. That config is our standard plug and socket! Saying that, the plug on that cord is REALLY old school.

Hi Robert,
Its an Obsolete US 220v 60hz plug, in addition to being the current standard Aussie Plug.
According to the Wikipedia link, you should be right to go.
Its also discussed in this link about the Australian wiring standard

Its a beauty.

That's a nice find!
Robert, If you ever want to sell it, let me know!

Thanks guys, so there is an Australian link to this oven then, that is quite interesting.
I'm still not sure if it is safe to use it on our 60 cycle system vs. the 50 cycle system that is is made for.

If you like Robert, Ship it over here and I'll fire it up and see how we go

Other than the cord and plug ..has the looks of a baby - no age showing

It looks like new.
I love Rummage sale finds and Robert also seems to find the most interesting.
Did the seller have any information about how it was used? Can you go back there?

Robert,
I'd be more concerned with running a 60hz machine at 50hz. The only real issue is how the transformer magnetics will handle the frequency difference. Moving higher in frequency is less of an issue typically. Since the difference is small (<20% ) just run it, I'm sure it will be fine.
Remember though that a 1 minute cycle will complete in 50 seconds for some odd reason

The oven should work OK on 60Hz-but as some others point out-the timers will run fast--unless you can replace their motors with 60Hz gearboxes.
220-200 Volt 50 cycle Amana RR-2
Cool Find Robert, this oven was made for European or Australian etc. use, someone must have brought it back from another country. It should be able to be used here, the timers will run about 15% fast, usually Amana used the same 60 cycle timer motors and just used different timer dials to recalibrate these units timing for OSU. We have seen a few Amana MWs over the years that have been brought back from other countries and had to do various things to make them work here.
The higher 240 voltage here will probably step the cooking speed noticeably from the orignal approximately 700 watts.[ This oven would really be better suited to run on our 208 volt supply at our Museum, hint hint.] But in any event it is a very early RR-2 and a really cool find.
I also have an early RR-2 without the buzzer and a flat glass tray that works, if it is easier for you to use I would probably trade you if that helps.

Looks Familliar
Nice score! This looks very much like the Euro RR-2 I posted to AW about this time last year, but we never got the nameplate on that one other than it was 220V/50Hz.
Other than faster times (as others have pointed out) there should be no problem running a 50Hz transformer on 60Hz. It's going the other direction that's a bad deal.
The original plug would have been molded with the cord, and the present plug is the old US 220V std so this thing likely saw some use here.
The HV output and filament voltages will be scaled on the secondaries of the xformers so there's no real cooking advantage over a 110V unit (note max current is 7.5A, approx half of the US version).
This makes number 12 of known RR-2's that have turned up in the last three years. -Cory

Great information guys! Thank you all.
Thanks for the information guys. Well now that we know that the frequency/cycles wont be an issue the next question is the 20 amp breaker.
We have a 220 volt 20AMP circuit outlet in the basement that I used to run the Asko washer on. I assume it is OK to run this then on a 20AMP breaker, or would it be safer to change it to a 15 AMP breaker?

The breaker is sized to protect the wiring that is run to the outlet, the breaker isn't there to protect the device being powered. Changing the breaker isn't necessary. The oven should(?) have an internal fuse/circuit breaker to protect it.
If you wish to be a somewhat cautious I'd clamp an ampmeter into the circuit to see what is happening for the first minute or so. But it will plug in and run fine is my bet.
