Build Your Own Clone Message Board

Okay, first off - most of my preliminary questions have been answered by the search function. Love this place.

I'm finally getting around to building the GGG four-output isolated power supply. I picked up the board and BOM courtesy of Stephen awhile back. Each output supplies 100mA. So, I can daisy chain a couple pedals together (yes, I know this kind of defeats the whole "isolated" concept) as long as the max current draw remains under 100mA. If I get close to 100mA, is there potential to damage something?

Hey, I've got an old PS PCB from Stephen too. I keep bumping the build for pedal builds.

Which build docs you got?

I'll show you mine if you show me yours

most likely you'd just burn out the regulators.

Depends on your regulator packaging. If your using the TO-220 version of the regulator your going to be able to source/sink 1A of current.
In the TO-92 (package were familiar with in pedals) I think the current is around 100mA but check the datasheets.
These regulators are designed to shut down, cool off then restart if they pull too much current and overheat. So the regulator should be fine.

It's the transformer you want to worry about. It has a VA rating that cannot be exceeded. If you try and pull too much current from your transformer you risk burning up the windings and destroying your transformer.

Simple solution is to add protection devices (fues, polarity protection, MOV, in-rush, etc.)

If you aren't going to use the PS as it was intended you may as well use a 1-Spot and a daisy chain cable.

Ahh, the voice of reason. Yep, I'll build this and run four pedals off of it as intended. If I dig it, which it sure sounds like I will, I'll look into putting another one/two together.

Those of you who have built your own power supplies, where are you sourcing cables? Or are you making your own?
