Requirements
Bipolar power
Enough power / planning
Clean power - The big discussion
Helpful components
Conditioning what you have
"Are linear power supplies better?"
Simple-ish practical supply
The quick and dirty starter
Probably the simplest decent option
On rectifier boards
Other design notes
On ground
On clean distribution
What's that about multiple cases and ground?
Other questions / Choices
Can I use batteries?
Aren't there readymade supplies?
Can I double up supplies?
From AC
Why 15V AC? Why not 12V AC?
Can I just use a single transformer?
Do I need a center-tapped transformer?
Could I use two 12V AC transformers?
Can I just use two 12V AC transformers?
Are there readymade bipolar AC supplies?
Can I just use a 24V AC transformer?
From DC
Can I make bipolar from two distinct 12V DC outputs?
Can I make two 12VDC from a single 24VDC supply?
Can I use switch-mode supplies?
Can't I just add linear regulators to switch-mode?
Can I use a computer supply?
Can I add more supplies to get more current?
Earthed or floating?
