Well, if this were my project, I'd take a look for
surplus
high-current AC tabletop supplies (transformers). I see that Jameco
has a 13.5Vac 5 amp table-top supply for $16.95. That's 67.5 W, if my
math is correct.
Since the 9VAC is used sparingly in the C64, a couple of 4 volt zeners
ought to take care of that part. As far as the 5V supply, a simple
rectifier+filter and buck regulator ought to get me there. The supply
is already UL/CSA approved, so no issue there.
But that's just me.

It is one of the ideas. I had been having trouble finding the high
amperage needed, but this is a nice component. Thanks for the link (as
it were).
My main concern was pumping that much AC into the 64, but it's
potentially not a significant issue.
I wonder if there is a 230V variant for the non US/CA/JP crowd.
