Seeking Mackie HD1531 P/S Schematic

[BMXMUSIC]

I've got a headache Mackie HD1531 that cuts the powers when the power supply board is impacted, even in the slightest way, but twisting the board and tapping individual components have totally inconclusive results... Reflowed everything on the board, traced as much of the board as I can see...I'm as far as I can go without a schematic. Can anyone help? I've only been able to hunt down that amp portion.

Thanks in advance. I feel scummy requesting files as my first post, but I'm stuck with a gig tomorrow night.

Call Mackie first thing in the morning - they are on Pacific time - when they open and ask for the schematics you need.

Tapping on the power supply may trigger this, but does tapping on other boards do it as well?
