[Hallicrafters] SX-23 Chassis

[Tony Casorso]

Well, corresponding with a fellow from another forum, we have determined 
that there are two versions of the chassis and cabinet for the SX-23. The 
earlier version of the chassis (which mine is) has only a half inch lip on 
the front edge of the chassis where the mounting screws from the fron panel 
thread into. It also has brackets for a small pulley and a trimmer cap 
welded to the back of the front panel. The later chassis has a full 4 inch 
front apron on the chassis and the aformentioned brackets are welded to the 
back of the apron. The older cabinet rear opening is too narrow by about an 
inch to allow the chassis to slide out the back whereas the new cabinet 
opening is increased enough to allow the chassis to be removed from the 
rear.  I am now pretty convinced that final wiring of the chassis, including 
the mounting and wiring of the bandswitch was done AFTER the chassis was 
mounted into the cabinet in my radio. The arrangement was bad enough to 
prompt a redesign. My serial number is H-89057 and the chassis is tagged 
with a signed paper inspection tag stamped April 10, 1939. The other fellows 
serial number is H-93416 ( a second fellow said his was H-93392 and also has 
the newer style chassis/cabinet).
