The Midwest 17-39 is a 17 tube, five band radio which features motorized push button tuning and and uses AFC during push button mode. This is the only Midwest model that features a multi colored, side lit, glass dial.  Manual tuning is added by a small window which states "Tuning" and is located just below the dial. The window is back lit and dims when a strong station is tuned in. This model features a full range 12 inch speaker and a 4 inch tweeter which is powered by push pull  6CA5 tubes. This is one of the rarer models of Midwest radios to find.
    I purchased this receiver, in April 2012, from Bob Poteet of Greenwood, Indiana.
