Each of these two heat sinks were made from 2+ each of DH-500 sink halves. I cut pieces on table saw with special blade then bolted sections tightly together with thermal grease at joints. Overall cooling capacity in excess of the DH-220/XL-280 sink. See comparison photo below.
Dimensions 9.25" X 4.25" X 1.75" (average fin depth) plus 3.25" overall depth with "wings." Each wing will mount 3 TO-3 devices so each sink can handle 6 TO-3 devices.
$40 the pair, plus postage. Calculate 6.5 pounds from ZIP 61111. Too large to fit in flat rate box so plan on Parcel Post -- unless you want something faster.

Here is an amp, a DH-120 stereo clone, made using a similar heat sink. This gives you an idea of how they might be used. Just excuse my lack of tidy wiring.
FWIW this stereo amp (60 + 60 watts) really cranks even with a high bias setting and the heat sink bearely gets warm.
