Hi looking for tech help

[n0ukf]

Hi from northern Minnesota (almost Canada).
I wouldn't call myself a bass player but I do have one to play with. My brother plays double bass for a local bluegrass/folk band. Years ago I helped him build a guitar amp from the old AX84.com projects and also built myself a little Firefly amp from there.
I found this forum while looking for schematics for a Seismic Audio FL10-MP PW powered floor monitor. The one we have at church just quit working and I don't know enough about class D amps to blindly find the problem. I don't yet see a general chat section here for non-bass topics.

Welcome to TalkBass!

Your query might fit in the "live sound" section. If nothing else they might have some familiarity with the brand and maybe have a contact for their service organization.

I've got a bit of an electronics background, but unfortunately this stuff is hard to diagnose, especially without seeing the service documentation. This is a "get in there with a voltmeter and oscilloscope" problem.

I'm still not seeing the "live sound" section in the forum list.
My electronics background never covered class-D amps but I have an idea how they're supposed to work (like switching PSUs). The only service documentation for these is probably at SA itself.
