The other day, I came into possession of this '46-'47 Admiral automatic 78 rpm suitcase portable record player. The amp uses 3 loktal tubes and there are two knobs on the front. One is for power/volume and the other is a motor switch. I fired it up and the amp will, of course, need a recap. The record changer operates as far as the mechanism goes; but, will need a new idler wheel and cartridge. In all my years of collecting, I've found lots of radio/78 phono combinations and mulit-speed phonographs; but, I don't recall finding too many 78 rpm phonograph only models.
