TODO updated, next up is cap and ground lift mounting. Then find fuse holders that are suitable. Lastly, I'll wire up the power supply and test that.
After that I wait for the heatsink to arrive, schematics to be drawn up, or do them myself, PCB layout to be done, or do it myself, then order, assemble, and enjoy!
NO! I _STILL_ haven't found any reasonable secondhand speakers to buy :-( This might be the biggest challenge of all.

- Bolt down both bridge rectifiers
- Figure out how to mount the filter caps and do it
- Wire up all power supply components and test
And then finally:

Heat sink arrived! It has a somewhat "Don't fuck with me!" look to it, so I thought I'd play the same part for the shot:
Usually I'm smiling in photos, so today I thought I'd be different. This is as close as I can fake to "Furious Fred" like the one that appears when people nearly run him over in Barcelona.

With that heat sink, I think you are covered. I would be more worried about gun smoke from your neighbors, after you turn the volume up
