I have seen some bad joints on some circuit boards, I used one of those usb microscopes, found a smd resistor that was shot.
So its a good idea to check these things, destroyed a few fets because of a dry joint.

There is some EGS002 boards for sale with proper capacitors on and I did see another board that had a 555 ic connected, still no schematic or description why its there.

I will be changing one of my EGS002 boards to proper caps.
