When I was in my early teens, I had an Air Castle radio I had rescued from the junk yard, and got going by replacing the electrolytics and the tubes with 'Used Tubes or Factory Seconds' I bought from Micro Electron Tube for 35 cents each. I do not remember whether the G type tubes were octal or pre-octal. The dial face was thick brass, with a swirled checkerboard pattern. I believe the radio had four bands. The radio used a two gang tuning capacitor; the IF transformers were large, and used litz wire. I think I remember that the rectifier tube sat on top of the power transformer, but I may be confusing it with another radio (after 50+ years.) I have tried to find the model number by looking thru the schematics on this site and in Ryders manuals. More than one manufacturer used the Air Castle brand; Spiegel was one, but I do not believe this radio was made by / for Spiegel. Any guidance you can give me in finding the model number would be appreciated. Thanks. Ed M
