Just be patient. Make sure there is some solder in your iron and if all else fails, cut it out and replace with a new part.

Hi Andy
Watch you dont put too much heat in to the copper track on the board you can damage that too...
Steve..
Yep will do have ordered a case from Aliexpress in the meantime Black Alu:)
Hi Andy
Aluminium is best suited for what your doing.
Aliexpress were pretty quick at delivering my cases.
Hope it's the same for you.

Hi Andy
I see you have fitted 1.8 ohm 2% resistors in the vital spot.
Should give you around 750 Ma.
Board looks good mate.
If your gonna have an led on your power switch you'll need to remove the single led and use that to power the front case light.

Just about finished my project with the addition of some 2mm aluminium angle under the Fets and across the 4 rectifier. Bought some 30mmx30mmx12mm heat sinks that are self adhesive and stuck to the aluminium angle. Fets and rectifiers are hot still but no problem pressing fingers onto them hard and leaving them there. Might get a couple more and stick them to the other side of the vertical ones on the rectifiers just to make sure.
I have 1.2R resistors and get about 852mA output from one side and 882mA from the other. Is it worth the effort to match them?
