Philco 643 color scheme and modification
#21

Ron Ramirez Wrote:If Bob's 643B cabinet has a hole in the side, it was added by someone after it left the factory - it did not come out with a hole originally.

I used to own a 643B, and it did not have any holes in its sides.

So since it is not supposed to be there for a pushbutton how does the dial light operate on these sets? Is there some sort of spring loaded switch elsewhere to preserve battery life, it can't be on continously?
