How to improve power supply?

My pre has a separate ps and it's very inadaquate.
It's from the mid 90's. What are the most important parts upgrades since then?

Rodman, I'm finally getting around to my gear as I may need to send my pre back to Spectral for some type of switch for changing phase. I'll research your info again and post more soon.
