Mackie D8B Digital Recording Console

[khowell78737]

For some time, it has been known that first and second generation Mackie D8B recording consoles had gotten a run of these bad caps.

Mackie isn't very forthcoming aobut which capacitors are the bad ones.

I was wondering if anyone here knew of this and how I'd go about avoiding the $800 service center repair charge (and the several months downtiime my studio will experience).

Thank you,

Re: Mackie D8B Digital Recording Console

welcome Kevin and thanks for bringing us something interesting. First i had to find out what it is :



so thats a $6000-8000 product with badcaps...damn that is cheap of them.

what is your question though? do you have a unit with badcaps or are you trying to find out if your unit has the defective brand of caps on it in order to proactively replace the caps before the problem arises?

i am doubtful if anybody will pass by with specific info on your console, you would be better asking on a mackie specific forum.

what i understand is that the console has a control surface which probably has a PSU. Then a CPU Box powered by a 300Mhz Celeron or Pentium 166, the CPU Box also has a PSU.

There will be capacitors in all of those locations. What we can do if you can take some photos inside the control surface and inside the CPU Box, additionally to record the values and manufacturer written on the side of the capacitors (the values are written like 1000uf 6.3V) then we can identify which capacitors are candidates for failure and should be replaced. We would be interested in all caps 1000uf and above. Also caps with lower than 1000uf but high voltage like 25V.

perhaps the photos might reveal some caps visibly failing.

would mackie still service the console later if an unauthorised technician replaced capacitors on the boards?
