E. H. Scott "Worlds Record Shield Grid 9"
Scott Transformer Company,
4448 Ravenswood Avenue,
Chicago, Illinois, USA

    There were two versions of this superheterodyne radio made, the 9 which had a 8 tube chassis and a three tube power supply/amplifier and the 9B which had 9 tubes on the chassis and no power supply/amplifier.  The 9 and 9B consisted of various lacquered finished copper boxes, housing the coils, audio transformer and the I.F. section with tubes, mounted on a Bakelite chassis that was either black or grey in color.  The R.F./OSC. section is tuned separately from the oscillator section.  This was Scott's first radio to use the new screen grid tubes (UX-222) that had just come out earlier that year.  I acquired this set in 1990 from a Washington State audio enthusiast in a trade for a Counterpoint D90 amplifier.
