I just realized that I flooded this thread with all my questions and since Mike kindly quoted all my posts I erased my original questions to shorten the thread.
I just got 21 stepped attenuator kits yesterday from CAPI and finished soldering everything this afternoon.
Also, I ordered 14x CM75101 and 14 CMOQ-2L from Cinemag and should recieve them this month.
I screwed the extra options (severely lacking money and need preamps!) so I'll do 3 rows of seven preamp cards with 48v, PAD and input Tx ratio. I'll flip the phase in the box when needed or built some xlr adaptor.
Here are the combinations I went for:
1st row (312) = EA2262 -> ML2520 -> EA2503
2nd row (Pacifi-kind-of... well, cleaner)= CM75101 -> ML2520 -> CMOQ-2L
3rd row (Cleanest-Hardy-ish...)= CM75101 -> ML918 -> CMOQ-2L
I think those combinations will highlight Mike's GREAT work with the opamps and ML12 pcb.
Anyway I have a bunch of pictures, will take more and will condense everything in one mega post with all the built process.... or wil make a new thread maybe if it's too long
Next will be sending the front and rear panels to front panel express.
