I made my own with a switching board supplying +5V and +12V and then a
simple transformer for 9V AC. All fused separately.
(12V isn't needed for the C64, but I also have a 1541-II).

yes there's a way, but I think you need an inverter-like electronics
with a transformer to float the 9V ac with respect to the +5V ground.
