Just a sanity check before I get the replacements I need.

Finding a "whistling" noise in the background, due to oscilation or summit with the Gator board / Murata regs...some research shows its probably the Murata switching noise being put into the audible range by the more open window of the Gator board - at least in my system.

So..
looking to replace the Murata's...
Sold on the Paul Hynes regs (Leo says they are the best he's used) here:

Have a linear supply with the Caiman so perhaps dont need to change both the 5v and 12v..?

Just a quick check as to what Paul Hynes Reg I'd need to replace the ones in the Caiman

...and do I need to replace them both?
I have a memory banging about in my bonce that I only need to replace one of them..if so what one?


Thanks!
