cheers ben,
as said to david i got to elaborate all this stuff and
i'm not that good at rework, just a better novice;
you said:
"I was forced to bend the leads of the switches and remove the IC
sockets from the PCBs under switches that I wanted to replace."

hu, that sounds a bit difficult to me, i think you mean
the left or right control panel where this happens?
hm if you drill holes, do you drill them in the membrane..?
but thanks anyway
harald
