[sdiy] That old modular power supply question (again)

[Julian]

Or at least a variation on it...

I have a (mainly) 12v system, currently running off a power one psu trimmed to 12v.

I want to add a 15v section.

I have 2 options -

To add another power one psu (which i have anyway) trimmed to 15v to power the 15v section, using a completely sepperate power 
distribustion board / supply.

To change trim the existing power one to 15v and then add regulators on each of the 12v distribution boards.


To me, option 2 seems like a better plan (although more work).

I can make up the distribution boards, and, id think that regulating down locally would give the best isolation between boards?  (im 
thinking bad doefper LFO modules that bleed onto the power rails)

I always hear of people running into troubles trying to power a modular with two power supplies also.

Anyone have any comments?

Thanks, Julian
