***** Line voltage is lethal. Always insure that no one can come into contact with it when used in your project. *****
This is a great bipolar power supply for your modular synthesizer project. This LM317/LM337 based supply boasts 1.5A capability and adjustable output so you can supply your projects with anything between +/-9 and +/-15 volts.
As you can see below, you will need to heat sink the regulators if you plan to draw the maximum power this supply can deliver. I would even suggest larger heat sinks than those shown. I made these from aluminum 'L' channel and if they start to get too warm as I add modules I will increase the size of them to dissipate more heat.
Also, single turn trimmers will work but multi-turn will allow you to set the voltage with more accuracy.
I list 10,000 uF caps in the parts list for the main supply smoothing caps and these will give you excellent supply smoothing but if you find caps that fit .4" spacing that are larger or smaller in capacity (3300 uF to 15,000 uF) they will still work for lower currents so don't get too hung up trying to find 10,000 uF electrolytics. I also list tantalum for some caps for best results but aluminum electros will again work as well. The more current you plan to draw from the supply the larger you should make the main smoothing caps.
