Biggest Sonys I remember were the 40" 4:3 and the 34" widescreens.
After delivering the first 40" we had a moving co move them, also the
34". We were getting old ! They were easy on an appliance dolly but
out of the box tricky. The 40" had to be strapped to a sheet of plywood
or the bottom could cave in ! That beast was so heavy it took 2 men
to move the matching stand. IIRC the stand alone was $500.
A widescreen 40" would be heavier due to all the extra glass.
I went to the seminar for that early RCA. It was named the "bat TV".
Worked on one. They had a cooling fan with a "wind" operated
shutdown circuit. I just changed the module. The trainer said so
much went into the set you could leave out 1/4 of the parts
& barely tell the difference. It was all out engineering.
Keep in mind when comparing sizes your source. In most other countries
they measure dead glass & other masked off areas. So our 40" Sony
was probably sold in Japan etc as a 43 or 44" set.
