A couple posts in the past, I mentioned paralleling LM317 regulators to enhance amperage output...
Here's my setup on a 1.2 -12v -- 10 turn pot variable " battery substitute " rectified supply that has served me for 25+ years.
It is used instead of endless AA's to power electronic flash units, the largest of which can draw upwards of 10 amps while charging the main capacitor.
Black square, is 2 layers of " aluminum perfboard " to cool the rectifiers, and the channel top right, is the sink for the regulators...
