xipica Posted June 8, 2020 Share Posted June 8, 2020 Hi, I have a DL4 totally dead. the board has p/n 35-00-0404 Rev A of 26 Oct 2012. The power section is completely dead, and I can't identify the 2 ic's, U23 and U24. The ic U23 I think is an RT7237, identical to the MAX887, the U24 I don't know what it is, it has a DL=3J526 identification. someone can help me? Does anyone have the wiring diagram for this card?

brujonica Posted April 6, 2022 Share Posted April 6, 2022 I'm currently repairing another REV A board, the PS is different as RT7237 pinout differs from MAX887, so not identical. Although parts designations differ between these boards and every other 4X4 board, that IC seems to be a MAX660. Seems that Line6 hasn't published support information for these board revisions.
