Yep, I agree that modular building and testing is the best way to go.
Also, we need to lay everything out so it is later accessible for repairs and modifications. I have seen a few rigs (including my own earlier e-rig) that was extremely difficult to work on. The ideal situation would probably be pull-out drawers. This time around I didn't even bother to tie wrap the wire harnesses. Anal wiring just leads to difficulty tracing and troubleshooting later on. I want my rig to be EASY to work on. 'Nuff said.
The latest E-rig innovation, digital drive, (with the homebrew analog VFO) is a nice addition. It's a more stable and reliable design. With this self-contained low level driver, there's no worry of blowing out the fets with a ricebox driver anymore - plus QSYing is a breeze without retuning the gate drive and worrying about imbalances, etc..
Looks like you have lots of room in there, Tina. I can see how it wud be easy to expand later on...
You even left on that $25 price tag in pic #3. I guess it doesn't cost "only $20 and a handful of Fets" to build a class E rig anymore...
