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?
