This posting is linked to my posting about use of this radio in the UK using a step down transformer
Thanks

The referenced schematic is a type of radio called the AA5, (All American, 5 tubes) and is no doubt the radio most produced radio in all of radio history. As it has no power transformer, you don't need to concern yourself about having 50 Hz power, just the 120 Volt mains. There is a lot of knowlege on this forum about thest radios. As the filaments are in series, all tubes must be in place and have good filaments before anything will happen. After that, you will find plenty of help on this site.

That extra RF tube will make this a powerful radio for picking up distant stations. Depending on your location, you may be able to listen to stations all over Europe. However, you should know that some areas of Europe use frequencies not available on your US radio.
FYI, the six tubes have all their heater filaments wired in series, like old-fashioned Xmas tree lights, so that the total voltage drawn is about 118 volts. There are 4 12 volt filaments and 2 35 volt filaments, 6 tubes, 118 volts.
If the radio does not function when it arrives, ensure that all the tubes are well seated in their correct sockets.
BTW, the Airline 55V181 pictured in the RadioAttic
http://radioattic.com/item_sold.htm?radio=1090327
has had its back cover repaired with a piece of stiff cardboard or hardboard. It needs to have those holes open to release the heat which builds up inside the cabinet. The back of that Bakelite radio is identically labelled and perforated as the wooden model Carl found for you, further proof that these radios are closely related.
The cabinet of your radio is most likely Bakelite, which can stand heat much better than modern plastic. However, heat is bad for the other components and insulated parts. Good luck with your new radio.

::Thanks Carl, great detective work.
::What I did not realise was that the same chassis is used for different cases, mine is a form of plastic rather than wood.
