Many thanks to all on this forum who helped me with my HB build. I love this amp. It has been up and singing for about five days now. I may up the bias a bit after a few weeks. The heat sinks stay below ~90ºF most of the time. Here are a few photos. I forgot and closed it up before taking a shot with the wiring cleaned up and secured. This is a dual mono build with two AN5445 500 VA, 45 volt transformers and two DIYAudio power supply boards with 54400 mf per channel for a total of 108800 in the amp. I used NJW3281/1302 for the outputs.

Here is my next Honey badger. It will take some time before it is ready. This time it will be a 2 ch amp to drive the fronts in my HT setup. And move the 5ch honey badger to center and 4 back ch. It will be a dual mono setup with a single 800VA 4x40V sec transformer and 80.000uF cap bank for each ch. The chassis is home made, build around a 3U modushop frontpanel, and modushop 3U 400mm heatsinks.

I think I used the 180mm for the platform and the 90mm for the side supports. I did have to cut down the side support risers to lower the whole platform. I bought a handful of the risers several years ago when I got the chassis and spent several hours trying out different possible layouts and mocking up ideas. With the two large transformers even the 5U box is tight. Notice the PSU boards hang off either side of the platform. I had a hard time getting the bridges and other parts and the platform all installed. Access to the trimmers on the amp boards is also limited - I use a plastic screwdriver for adjustments and have to contort my hands to hook up probes.....
