hey don,
if it's the one I saw it's a few dozen teeny SMT resistors on a pc
card to get a DL that can handle around 5 watts.  First thing in my
mind was shoot, I'd go downstairs to a bag of 2 W 200 ohm carbons, and
fish out four, drill holes in that kit pc card, solder 'em up  and
call it good and done.  screw that SMT %^&*.
