Switching from neg. to pos. ground

[1wahfreak]

Can some one point me in the right direction for this conversion. I searched the FAQ but all I found was switching from NPN to PNP.

Changes includ Diodes, transistors caps and the PS itself.
 The pots, resistors, [what else hmmm], should stay the same.
 Basically anything polarized should be looked at, and reversed.
