anything. If there is no change, that would tend to eliminate the drive signal as a source
of problems.
Some devices are simply very sensitive to ANY stray capacitance between the input
and output sides. Some devices are extremely sensitive to interference coupled to pin
7, which (unwisely) provides a connection to the photo-transistor base. To test this as a
possible problem source, try snipping off pin 7 on your device and see if that affects the
results beneficially. If it does, you might want to consider designing your own ultra-low-
stray-capacitance socket and daughterboard, or avoiding sockets entirely and using
soldered devices instead.
