The manual says not to open up system to change fuse. There is no info
in Manual. Has anybody changed fuse in Mackie Hard disk Recorder. And
is it a standard fuse and if so what size. Is it easy to get to?
Thanks

I forgot to say this is the Mackie SDR 24/96

For the most part, fuses don't blow without a reason. But if you get
the full service manual, it will show you what's inside the power supply.

I haven't changed fuse in mine but I had it open once and in order to be
able to get it back in one piece again I took some pictures. There are
about two zillion screws. Once out you can take the cover off and see
see this...

They probably say that because a fuse shouldn't blow in normal usage. A
blown fuse in modern gear designed to safety standards indicates a fault.

Sometimes the fuse does just get 'tired' though and blows. More likely with
cheap ( read Asian ) fuses. My latest stuff tends to have internal fuses.
It helps stop ppl putting the wrong value in and then *really* cooking
their amplifier or whatever.

Graham, I know you Brits have different meanings than us yanks for various
words, but I've never heard "whatever" used before when the meaning was
actually "their ****ing house".

The capacity of Englishfolk for ironic understatement never ceases to
amaze me.

I have to apologize after it was brought to my attention that there is
only one remote jack on the SDR. The warning not to plug into the
internet jack is on the remote control. So I do not remember now if I
plugged the remote unit into some other gear accidently that was an
internet jack and then plugged the remote unit into the SDR.

So the bottom line is, my Mackie SDR will not turn on (embarrassed)

1) The power supply looks likes a 'regular' switch-mode PC supply,
separate enclosure bolted in the cabinet, with typical main
board/drives/etc pigtails...

2) You'd have to pull out the power supply, then remove its' separate
sheet metal cover get to get to whatever mains fuse it may have. FWIW
9 out of 10 times here, if a switch-mode PC power supply has "blown its' fuse", there's a hard reason that needs to be repaired before stuffing another fuse in (shorted secondary rectifier diode, shorted input bridge, shorted switch mode device, etc.)

FWIW2 unless you're familiar with PC repair/parts handling techniques,
I wouldn't recommend 'messing around' inside; lots of static sensitive
stuff in there!

Ahhh - that's probably because we don't get many house fires here ( let alone
caused by electronics ).

I understand that US homes are more flammable ( lots of wood etc and slightly
dodgy electrics ).

That's because it isn't a service manual and they don't want you to
get electrocuted.

Open the case, find the fuse, look at it and determine its rating. Get
a replacement and stick it in. Don't do it with the power cord
connected. While the cover is still off, plug it in, try it, and see
if the fuse blows again. If it does, something else is wrong (which is
usually the case when a fuse blows).

If you don't feel comfortable changing a fuse without detailed
instructions, take it to a place that services this sort of equipment.
But if there's something wrong that's causing the fuse to blow, you'll
almost certainly have to take it to an authorized Mackie service
center.

Most times when I have changed the blown fuse on a switch mode power supply,
connecting to the mains and switching on again has resulted in a very loud
bang and bits of components hitting the ceiling.

Spectacular.

Check the fuse first...if the glass is coated with shiny stuff (that's a
technical term), there probably is or was a sudden short circuit somewhere.
If you can see the remnants of the fuse wire through mnostly clear glass,
then it just failed on its own or the problem isn't as serious. YMMV, and
ohmmeters are quite useful, especially for checking rectifier diodes.

Dunno about 'changing' a fuse. But 'replacing' it is straightforward.
However there is probably a reason why it blew. Mackie's advice is to
disuade people who don't know what they are doing from causing further
damage to the equipment or themselves.

Fuses can fracture, or blow with a mains transient, so there is no
compelling reason not to open and replace the fuse with the SPECIFIED RATING
AND TYPE . If it blows, then the device definitely needs qualified
servicing.

But if you need to ask, then maybe it's better to get help...

Half the voltage and twice the current makes things a bit more marginal too.

That is because a certain amount of common-sense is generally (but not
universally) attributed to those who understand the mother dialect. Firemen
need work too.
