Troy:
Yup. Four pieces of 1/8" thick aluminum and two 1/8" thick "L" pieces, all from my scrap collection, plus very thin layers of thermal compound. Tightly compressed using three bolts in addition to the two used to mount the amplifiers. Vindication that hoarding junk sometimes pays off (not exactly my best brag).

For all the people who have PCBs for this project hiding away in the pile of things to build, and then got thier plans crushed by the semiconductor shortage, Mouser has LM3886 IN STOCK right now.
https://www.mouser.com/ProductDetail/Texas-Instruments/LM3886T-NOPB?qs=QbsRYf82W3EwP/XUhaZp9w==
Lead time is stated at 87 weeks, so if you miss this batch, you’ll be waiting almost another 2 years.

Now that the LM3886 is easy to come by, I was wondering if anyone who participated in the original group purchase of boards ever completed this amp project. If so comments about how your build went, problems, and performance.
Hi, sorry to bother you, I just finished building the amplifier, the sound quality seems decent to me, except that I hear a slight hum at 50Hz I think, I've tried everything to fix the problem (ground loop breacher , etc.) but nothing changes. The diagram I followed is attached. Thanks in advance for the clarification."
