Welcome here Bill,
Model 90 was made from around May 1931 until April (or so) 1932, in three distinct chassis versions.
Early version - two 45 output tubes, a "Normal-Maximum" toggle switch in back
Middle or most common version - one 47 output tube, no switch in back
Late version - two 47 output tubes, three-gang tuning condenser (first and middle versions had a four-gang tuning condenser)
Which one do you have?
