Hi guys,
Have a DWM4070NV2 driver board from a Ground Zero GZPA 1.10000SPL to rebuild.
L2, L3, L4, L5 are all burned beyond recognition - what values are those inductors ?
I'm missing also Q2 + Q10 ? Are those the same as in DWM3640 marked as "MAX" transistors or not ?
I know driver board looks badly burnt, is there a place where a new driver board can be bought if i won't be able to repair this one ?

Yes on Q2 and 10.
You'll have to scrape away all carbonized fiberglass.
I don't think the inductors are critical. The only OEM diagram I have (for a 3640) shows the inductors as 1uH. Someone who drew a 4070 board has them listed as 0.15uH.
