All transformers are "unique" in that there isn't a simple list of standard
transformers that everyone uses, like resistors. You could certainly find a
substitute that would work okay (although I doubt you need one), but I doubt
it would have the same mounting hole spacing, or be exactly the same rating.
The other parts, including the ICs, are things you can easily get exact
replacements for.

Yup. I wish someone with access to silkscreening equipment would make some
replacement membrane switches. A lot of people around here seem to need
them.
