Those are pretty awesome heat sinks. If I had a set of those, I'd probably build a variation of the BA2015 50W Schade / Singing Bush amp. Single 60V power rail, 3.2 Amps Iq or thereabout. Could be a lot of fun.
Actually, I'm gathering parts for a Singing Bush as we converse. I already have a set of big hockey puck Mosfets & SITs. Now I need ZM to come through with the PCBs. 😉
Perhaps I should seek treatment.

@Tungsten, I heard from some folks around here that building amps is good therapy 
@KatieandDad, beautiful amp! Proof that recycling is good for all of us

There are loads of industrial heatsinks, it just takes a bit of imagination as to how to use them in an at home design.
I eventually drilled out those holes in the sides of the heatsink and fitted internal braces to hold the case together.

Friends years ago gave me a "professional dumpster diver" certificate. Lots of opportunities on a round the world sailing trip. The best area for dumpster diving for electronics in my experience was Europe. Was because of recycling, and now those dumpsters are generally locked up. Ah, the memories. I remember a particular event. One was a bank revamping it's entire data center. Over the weekend the dumpster was left on the street. Now this was a real gold mine. The dumpster was huge as you had to climb a ladder to just see what was in it(full). Eureka, the mother load. I have some scares to prove crawling through piles of circuit board is possible hazardous! With experience you get more selective in what goes home.
I have built an ACA case out of 3 sets of heatsinks, equiped with foil resistors, and film foil caps recovered from dumpsters.

Hmm, quite a task to recycle those. Mine were a bit easier to re-use.
Has anyone bought the Aleph J boards ? Are they single or in pairs ? I might have inadvertently bought two pairs of boards.
There is also the Aleph-X, which could make use of two pairs of Aleph J boards and even that second set of heat sinks.
