And for anyone with existing "standard" diyaudio UMS heatsinks:

For 1 Channel. All boards have some common holes that line up with UMS so getting started with the PCB as a template is easy.

300mm deep:

EF3-3 with TO-3P outputs - no drilling required
EF3-3 with TO-264 outputs - 6 additional holes (outputs)

400mm+ deep:

EF3-3 with TO-3P outputs - no drilling required
EF3-3 with TO-264 outputs - 6 additional holes (outputs)
EF3-4 with TO-3P outputs - 6 additional holes (pcb and drivers)
EF3-4 with TO-264 outputs - 14 additional mounts required (pcb, drivers and outputs)
EF3-4 with MT-200 outputs - 22 additional mounts required (pcb, drivers and outputs)
EF3-5 with TO-3P outputs - 16 additional mounts required (pcb, drivers and outputs)
EF3-5 with TO-264 outputs - 16 additional mounts required (pcb, drivers and outputs)

I would like to get a chassis on order but I have yet to see the BOM to know how to select transistors and their associated packaging. Any guidance on which transistors to choose and their package? Also what is necessary to order from Modushop a chassis for a EF3-4?

Does anyone have the CAD models of the V5 EF3-5 boards. If there exists the models for the supporting boards in the V5 set I'll take those as well.

I am one who likes to CAD everything up before I start to order parts.

Give me a few days and I'll create some dxf and step files for you of all the v5 boards.They will only show the board outlines and mounting hole positions.

I'm the same,I like to lay everything out in CAD before I start.

I'll update the first post of this thread with that information a little later today. So please check again later.
For now here is the modushop heatsink link.

Fantastic. All I really need is the DXF and thickness. I can finish the rest off in CAD. Once I finish the design I'll just upload it for anyone for anyone to use/modify.
