Cslim,
Great suggestions. I think I will combine a version of 1 and 3. I will buy steel "mending plates", the kind that look like door hinges but are really just steel plates with holes. Drill new holes to line up with the screws. And use this DIY steel strap to hold a copper plate against U800. Will probably put a bit of thermal grease between the copper plate and U800. I will taek pictures when I have this working. Thanks for a great idea(s).

I do it three quick and dirty ways:
1. Buy suitable door hinges. The two screw holes are offset nicely. Get
the right ones, add heat sink and screw into the stud(s) to seat them flat
on top of u800. Add washers, or screws, where needed.
2. in DIY shops, buy tags with two holes, similar size to large paper
clips, and screw them on.
3. My favourite- get small thick copper plates , a little smaller in size
than u800. Get some valve/tube solder lugs. Use the lugs to solder onto the
cooper plate to hold the copper plate in place.
As long as the height of these heat sink does not exceed the height of the
two side screws, no fear of shorting voltage to casing.

Hi Steve,
Here is one possible solution:

Basically a low-profile heat sink is needed that will not contact the
cabinet bottom.

I've seen reference to additional cooling for U800 in several postings.
Is there somewhere on the internet that suggests how to go about doing
that?
