I've found it on a few of my TS-18 chassis too :yes:

They didn't send the misswired chassis or any other rework to the original assembly worker. It would mess up the flow of product through the plant. Most firms had a repair line, where an error was corrected.

Then who was the stickers intended for, the original build line in hopes no mistakes were done or the repair lines in hopes they get it right....lol

I picture big banners hanging from the ceiling with the same "Do it Right" message, maybe pinback buttons, posters, etc. Maybe an employee newsletter featuring cartoon characters, "Mr. Right & Mr. Wrong". The latter character is always wiring electrolytics in backwards, etc. So says my imagination, anyway!

The only thing that i could think of as for the reasoning behind the stickers is that they are a reminder to every assembler on that production line to do the job right. if you notice where the sticker is placed, you will see that it is the only open space on the chassis that the sticker could be applied. it must of been placed on the chassis before any of the parts were installed. apparently, the tuner switch was the last thing to be installed on the chassis

There was less room for error, with the early Motorola chassis, as the tuner was part of the main chassis. You didn't have the option to change the tuner, if defective like Admiral and most of the others.
The selector switch and coil assembly, was probably built in another area of the plant, as Motorola made many of their own parts.

That could work two ways. The message "Do it right", could have a negative message to a visitor or a potential customer. It shows that the firm has a lot of quality issues.
The best way to do that is a message on the bulletin board. There was one in every department. :thmbsp:

They probably were told to do it fast as well. Which can conflict with "do it right"... :D

Mass production of the day,lol,lol...

I found surprising statistic in a 1951 issue of the Sams PF Reporter. Maybe the "Good old days" were not so good....

DEAD ON ARRIVAL. According to the National
TV Dealers Association, one-third of the TV sets
produced were not in good working condition when
delivered to dealers. This figure is bad for TV dealer
overhead. The public, forever clamoring for discounts,
doesn't realize that just making a new set
work takes a big hunk out of the dealer's margin of
profit.
