Mackie say this is not a user service part. If the fuse has blown there is probably a fault in the unit being their reasoning. I know for certain they tend to blow for no apparent reason so it is worth giving it a go. They are 5 x 20 Slow or time fuses. 7A for 120V and 4A for 230V

If you've changed the tweeter and the sound is still muffled the fault is with the HF amp, or the cross-over. You will have to send the amp assembly for repair as it is all surface mount components in there -nothing you will be able to fix yourself. Sorry for the bad news!

Getting very muffled sound usually could be attributed to either the cables supplying the speakers being bad or torn speakers. The cable problems usually should be traced as far at where they get connected to the unit as a breakage in any of them could cause such problems in the speakers.
Secondly the main speakers in the speakers could be torn therefore the bad sound being produced try to get all the component speakers checked to ensure that they are all okay. if after checking these the speakers are found to be good then try an alternative sound souurce to ensure that the problem is not from the sound source instead of the speakers.
Hope this solution has been helpful?

Chances are if the fuse has blown, there are failed electronic components that caused the failure.

Here is a service manual that will be CLOSE to your unit, though not exact:

Scroll down to the "Get Manual" on the site and click on the link. The file is compressed. The first part is the schematic, the second the assembly and parts list. Likely the main low freq power amp has shorted transistors.

There is an entire crossover circuit inside that is BEFORE the amp section. There are 2 separate amps: one for HF and one for LF. Can you describe the noise you are hearing in more detail? Is hte sound effected by the gain controls at all? What happens without any input?

Thanks,
Dan

You probably have issues with caps in the power supply....I would check that first...open it up and look for buldging caps and replace any that you find....

First thing to do is get a can of contact cleaner. Take off the knobs and spray it into the reostats below. Spray into all the switches and even into the sliders. Move everything back and forth - 0 to 10 (to clean them). If we're lucky, that will fix it.
Good Luck

First, unless you are a trained or self-taught audio technician, don't attempt to repair the unit yourself. Let the professionals repair it. You can damage it beyond repair if you don't know what you're doing.

Non-working channels are caused either by bad connections, bad solder joints or a dead IC op-amp.

The causes of weak channels can be more challenging to track down. I'd suspect bad connections, dirty controls or connectors.

Glenn, Does it say 'overvoltage', or simply 'voltage'? For the clearest result brother, contact Mackie - 1-800-898-3211 is their tech line - they're super cool - I just always picture the guys at Mackie sitting around reading comic books and shooting guns into the air. good luck!
