Archibald only works on 300ma power supply, not 500ma?

Hello

As the title says, my Archibald only works on 300ma power supply, not 500ma. Does anyone know why this might be?

I have been troubleshooting this thing for a while as it intermittently works and doesn't work. Today I finally figured it out. I have a power board that has 7 jacks @ 300MA and 2 @ 500ma. It works depending on which I use.

At 9v the 300ma dc input jack measures 9v as it should. However the 500ma measures about 2.4v.

The build doc says it should work on 500MA (and should work better) so i'ma bitconfused. Plus itused to work in the 500ma jacks as these also goto 12v.

Does anyone have an idea why this might be?

Are the mA ratings per output or are they shared amongst them and do you have anything else plugged in simultaneously? There should be no operational difference between a 300 or 500mA output so this is curious.

It is weird

Here is a video link. The 3 jacks on the right are all 500ma. They don't seem to register the input and the led doesn't turn on. These jacks work fine for other pedals as you can see.


The 7 jacks to the left are all 300ma all work fine on the Archibald.

The ma ratings are per output and there is nothing else plugged in at the time of the test.
