I think you'll find, if you read through the rest of the messages here dealing with similar topics, that the 6500 power supply is far too big to fit into the CC if you don't also replace the CRT with an LCD screen. John Stocker is the resident expert on those, so look at his posts first. I think Stuart had suggested trying this about a week or so ago and John said that the PS just wouldn't fit without much more trouble than it was worth.

If you're handy with a soldering iron and have some spare time, you can probably find the 3.3V regulator IC on the 6500 power supply, remove it, and build your own regulator circuit based on that. It might even be laid out simply enough that you can just cut out the 3.3V regulator circuitry from the board inside the power supply and hook up a few wires and be finished.

Anyone wanna donate a working 5500/6500 power supply to me so I can find out if this is a viable alternative to building a regulator circuit? :) One of the obvious benefits I see is that you know the regulator works, and you know it's the right regulator :)
