This is one of a number of vintage tube. They all were from the estate of a ham enthusiast who collected and. Rebuilt communication receivers over the years along with many other tube type radios and test equipment. Here’s 1925 MIRACO (Midwest Radio Company). Ultra 5 battery operated radio. This set was made in at least three different versions and this is the scarce earliest version. It features the gold MIRACO decal on the front panel. These fragile decals are almost always partly or mostly missing but this one is near perfect. It also has the early “silver” rheostat dials also in great shape. The mass market radio boom of the 1920′s. I downloaded a late 1924 magazine advertisement for this set (see photo) for you to look at. This set is in its original. Wood cabinet with its very good original finish. Condition is very good, the wood cabinet is original with a good 100 year old finish. The lettering is original and still legible. The dials, knobs, and controls are all in good condition as far as I can see. The chassis is in good condition. As you can see. I know very little about this set and no testing was done. The set requires five of the 1920s. Please look at all the photos as they are an integral part of the description. This is a long rectangular set. 28 x 8 x 10 approx. Set weighing about 25 pounds securely packed and boxed. Again, please look closely at all photos. As they are an integral part of description.
