That's a little misleading, Greg. The S-27 used the same acorn tubes
n its front end as well. The primary difference between it and the 36
as the addition of the radiation suppressor stage, and a slight shift
n band coverage.

 S-36A: 27.8MC to 143 MC in three bands; 5250KC IF; 954, 955, 956 accorn tubes 
n front end

 S-37: 130MC to 210MC in one band; 18MC IF; 954, 954, 954, 955 accorn tubes in 
ront end

 The S-37's 18MC IF frequency is interesting and it has no bandswitch featuring 
ne continuous tuning range from 130MC to 210MC.
