Heat Sink

Last of the bunch.  The last ones are unwrapped and a bit dusty.

Black, anodized, aluminum heat sink. Made in the USA.

Several years ago, we made our own amplifiers.  I happened on a box full of unused heat sinks.  If you have a project in need, these are pretty nice.

They measure 5.5″ wide by 6.125″ long and the fins are 1″ high.
