Cracking open a Galaxy Audio PA amp

[David Nebenzahl]

I inherited a repair job that I can't get started because I can't get
the damn amp open.

It's a Galaxy Audio Core PA5X140 all-in-one PA. It's a tough little
unit, with a die-cast metal chassis set into a thick rugged plastic
(polypropylene?) case, that can sit on top of a mike stand. Similar to
this one: http://galaxyaudio.com/MSPA.jsp. The front of the chassis has
6 screws into the case, and there's one on the back I removed, but I
still can't get the chassis out of the case. I tried prying the case,
thinking there might be some cast-in lugs I could open, but no luck, and
I didn't want to risk chewing up the edge of the case.

Does anyone have any idea how to open up this unit?

Specifically, No....But I have sometimes found that they like to hide screws
underneath the pasted on rubber feet, so you might investigate that. Also,
inspect the cover carefully to see exactly which panels are welded to what
other panels, and you might get a clue as to where the screws have to be in
order for it to come apart......

Nope, no feet on the bottom.

Nothing's welded to anything. Just a diecast chassis set into a plastic
case that surrounds it.

I have noticed that sometimes there is a screw (or more than
one) under one (or more) stick-on label(s).

Good idea, but no screws lurking underneath labels here.

Try emailing Galaxy and asking them ? They can only say no ...

Head up your email "Urgent - Please Pass to Service Department" You might
strike lucky and get a secretary that prints it out and passes it on without
'filtering' it. In my experience, most engineers don't mind helping others,
and unless the company has a really strict 'no help' policy, quite often if
you can get as far as direct communication with an engineer, you can get the
information you need.

Sometimes loudspeakers (I see this product as a powered loudspeaker) are
entered by removing the largest driver.

Sorry, not helpful. Everything, including the largest (and only) driver,
is behind the diecast front panel/chassis. Nothing accessible from the
front except for the 6 screws I've removed.

Thank you for that. I know I'm certainly not alone here in my opinion of

Fine idea, and was my next tactic. As you say, what have I got to lose?
It'll be interesting to see what kind of response I'll get. I've had
good luck with this approach in the past.

Hi!

to lose?
It'll be interesting to see what kind of response I'll get. I've had
good luck with this approach in the past.

It will be interesting. Please do post back with their response.

Looking at the unit, I wondered if perhaps the cabinet was snapped
together internally at assembly time. I saw what to me looked like a
seam line, but the photos weren't really high resolution enough to
tell.

If that's true, it may mean that opening the unit will mar the finish
or break some/all of the things holding it together.

Try fitting a piece of paper through the crack to see if it really is a
separate piece of metal.....Reminds me of the wooden beams that "hold up" my
living room ceiling.....Until I was able to put a sheet of paper between the
wall and the end of the beam.....turns out that its the other way
around....The ceiling is holding up the beams....:^)

A ring cutter yes, as a last resort, to make an inspection hole.
Somewhere there is unlikely to be active stuff and where a blanking plate
could be fixed over the hole and maybe another hole if the first reveals
nothing useful. Where an "endoscope" would be useful.

I'm assuming you've run a piece of rounded off dowel over any decals for
covered screwpoint recesses.
