I had googled "mackie disassembly" to no avail. I removed the bottom plate and found that the main pcb is soldered onto the top plate in around six places. Is the only way to get access to the capacitors through desoldering these points or is there a special screwdriver that can remove the non-phillips/non-flathead screws that seemed to have bolted the pcb to the top plate?
Before I proceed with disassembly, I think I may have located the source of the problem. Oh right, I should probably mention what the problem is. The mixer gives off a faint sine tone that occurs persistently. I think the other signals also come out significantly muted. My guess after having glanced at it is a problem with the transformer or whatever it is that the pictures below are of. It's directly related to the power jack and I noticed a build up of crud around the plates. I'm thinking that something leaked around that area and whatever it is, it needs to be replaced. Pictures complete this and more can be taken upon request:
and here are the solder points/bolts
Also, I hope this is analog enough to stay in this forum. If not, I understand. Thanks.
