The TO39-AMP (40 Output Transistor Fun Project)

This is fantastic. I’m only just starting my design journey and am only recently feeling comfortable with an LM386 (😆) but this such an inspiration! I have hundreds on hundreds of TO-39 and I’m itching to start playing with them. Thank you for posting.
 
Not really.
All PCBs are temporarily screwed onto a base plate and connected, everything works perfectly and is used occasionally. No changes to the circuits are planned. Everything just needs to be in a housing. Since this isn't supposed to be a simple cuboid and I'm going to build it myself, it will take some time.
