The tubes stick out on the bottom, but that doesn't matter as it all
There are 17 X 155mm tubes in each condenser. That 2.36 mts of cooling tube in each.
I used 15% silver solder (Prosilver 15 by BOC). It's slightly more expensive than the standard 2% stuff but flows much better. I found anything more than 15% silver has CADMIUM in it. Always check the manufactuers tech sheet on the solder you use as many silver solders have cadmium in them to make it flow better.
EAT CADMIUM AND DIE!
