If U1 pin 11 is near 0V and pin 19 of the KB Controller IC is not, then,
there is either a break in the line connecting the pins or one or both IC's are
making poor socket contact.
If pin 19 of the KB Controller IC is near 0V when the CTRL key is not
pressed and near 4-5V when the CTRL key is pressed, then, if you still have
'stuck CTRL key' symptoms, there is a good chance that the KB Controller IC is
messed up.
Note: all of this assumes that your KB is like the one diagrammed in the Apple
][ Reference Manual on page 101.

015- Can I replace my bombed IIe keyboard with one from
another IIe?
All four styles of the early keyboards are interchangeable. The first
production machines have the keyboard mounted to the base pan while later ones
are mounted to the underside of the top of the case. The mounting holes for all
the keyboards except the platinum models are located the same.

016- At my school we have a IIe that has some problem
with its keyboard. When you push a key it keeps on
repeating until you push another, which also repeats. Is
there a cheap easy way to fix this?
My experience is that this is more simple than it looks. You have one stuck
key. It is stuck down. Have you opened the machine and moved the keyboard? If so
you may have replaced it wrong, it is rubbing on one of the edges. The key that
is stuck is next to the edge.
If this does not apply to you, often pressing all of the keys until it
stops (because by pressing on the right key, it comes unstuck) will work.

My first suspicion is a stuck key, and if this is a beige ][e, the first
place I'd look is the [`/~] key, adjacent to the power light.
