Default Cracking open a Galaxy Audio PA amp

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?


I have a Core PA5X140 hot spot sitting in front of me.
single 5" speaker with amp built in. It really did not want
to open either. It has 6 screws on the front.
a screw on the back. On this unit, there are 1/4" phone jacks on the
rear. These are connected to the internal circuit board. SO, the lock
nuts MUST be taken off the phone jacks before you start the removal process.

On this one, the front face is inset down into the rear shell. My guess
is stictation or such is a factor. First on this unit, i gently pried
around the deal with a razer blade. Then i used a very small flat blade
screw driver to try to break loose the case from the front. Then i kind
of beat on it to see if gravity would help it separate (face down). I
eventually got it apart, but it did not want to easily separate.

Thanks for the first and only really helpful reply in this whole damn
thread.

You, sir, are a gentleman and a scholar. Sure enough, removing the nut
from the phone jack allowed the whole unit to slip rather easily out of
the case (I used a heavy knife blade betwixt the case and chassis to
start it).

The amp appears to be fine; there's either a problem with the XLR mike
input jack, or with the mike cable we were using. (Can't test because I
have no XLR plugs.)

Thanks again.

Hmmm. I agree that is a little fundamental. I thought we were looking at a
'real' puzzle here ... And without an XLR balanced / unbalanced signal
source, how can you test properly, without making possibly unfounded guesses
about the service condition of the mic or its lead or the socket on this
amp. I would have thought that this sort of test would be fundamental before
wasting time trying to rip it all apart. It is in my workshop anyway.

Its not really self evident that the jack is connected to the PC board.
When i took mine apart, i certainly did NOT think it was that way. I
eventually figured it out, but it took a while. i assumed it was just
a raw jack connected with loose wires to the amplifier.

This sort of assembly is not that uncommon, as it reduces manufacturing
costs. It also makes testing the amplifier a bit easier. I've seen expensive
equipment that did the same thing, making the device virtually
unassembleable.

Its always a challenge these days to get apart some modern
"Unfixable"electronics. They really don't want you to fix them or
open them up. I sometimes get LCD monitors with issues that i
try to fix. Its always a game to figure out where on the case
the latches are on the clam shell and to pry and not bugger up
the case too much. I usually get them apart, but sometimes
there are "battle scars" in the process.

Even some remote controls are not the easiest things to open up.
I solved that by just giving them to my wife. She gets mad
and throws them at me and they mysteriously open up in parts...


the real fun is trying to get a power supply or such apart that
is spot welded together or glued. Thats more of a 50/50 deal
if you can get it apart without destroying it.

I like a good joke as much as anyone else. But when someone ask for help
and is maybe not a expert at least cut the guy some slack. Give an
answer and them make the smart comments.

I feel stupid for not suggesting removing the nuts on the phone jacks. I've
seen this done sooooo many times.

I can't remember the last time I saw a phone jack that *wasn't* soldered to
a circuit card.

Me neither. Now that I've disassembled this it makes perfect sense, as
it allows the amp to be put together in a neat package with no external
wires except for the power cord.

With the 6 front-panel screws and the phone-jack nut removed, it's
actually *very* easy to disassemble. Not a hard nut to crack at all,
like so much other plastic-packaged electronics.

Look, you little **** (and keep in mind that *you* were the first one in
this thread to use profanity): let me explain my situation for your
little pea-brain to understand.

I am not a professional electronics repairperson. I don't maintain a
repair shop, nor solicit repairs. This is why I own no XLR connectors:
normally I have absolutely no need for such things. I have no sound
equipment, microphones, etc. This one just landed in my lap. I used to
be in a band, the leader of which just recently died, and when we tried
to use this amp at a gig, it failed. I offered to diagnose it and
determine what was wrong with it.

I'm 99.99% sure that the problem is outboard of the jack connections on
the amp simply by doing the "touch the input connection and listen for
hum" test. The amp responded admirably well to this test, so I'm certain
it works. The problem, then, is obviously either the jack on the amp or
somewhere in the microphone cable being used. There wasn't enough time
to get another cable and test it.

So if you want to continue to berate me for some perceived slight
against the propriety of this newsgroup, which after all is supposed to
be a source of information for people seeking such, well then, go right
ahead and be my guest.

Just wondering why you decided to inject the adjective "professional"
into this discussion. As the OP, are you suggesting that my application,
or the equipment associated with this amp, are "professional"? Because I
can assure you that we (the band that used to use this amp) are pretty
close to 100% amateurs (of course in the best original meaning of the word).

I'm not sure I would even classify this amp (Galaxy Audio Core PA5X140)
as a "professional" piece of equipment. Though it does appear to be very
well built: I guess you could drop it two or three stories and it still
might work.

Look, you little ****


Is that the BEST you can do? C'mon! Work with me here!

(and keep in mind that *you* were the
first one in this thread to use profanity)


OMG! Profanity on the Usenet! My transgression is
unforgivable! Please have the mother****ing pigs come and
arrest me STAT!

let me explain my situation for your little pea-brain to
understand.


I have a HUGE head, I can never find a hat to fit me. And I
have an IQ of 134. Not THAT high, but odds /are/ it's higher
than yours. OTOH, head and brain size have nothing to do with
intelligence.

I am not a professional electronics repairperson.


Neither am I.

I don't
maintain a repair shop, nor solicit repairs.


Neither do I.

This is why I
own no XLR connectors: normally I have absolutely no need
for such things. I have no sound equipment, microphones,
etc.


I used to sing (using the term loosely) and play guitar
(etc.) in bands, so I have a ton of XLR (and other)
connectors and cables, etc. I understand not everyone has
such items on site.

This one just landed in my lap. I used to be in a
band, the leader of which just recently died, and when we
tried to use this amp at a gig, it failed.


It's not a bad idea to test other people's
instruments/equipment before using them, let alone WHEN DOING
A GIG.

And there were NO other cables on the stage at the time, huh?

I offered to diagnose it and determine what was wrong with
it.


Hmm. So you ALSO used to be in a band, and you don't have a
single XLR cable in the house?

Hmm. What kind of band?

I'm 99.99% sure that the problem is outboard of the jack
connections on the amp simply by doing the "touch the input
connection and listen for hum" test. The amp responded
admirably well to this test, so I'm certain it works.The

No, of course not.

I am not berating you, I understand why you posted your
question here, but you or someone you know DO have a digital
camera, you DO know how to use the internet, and you SHOULD
HAVE CHECKED THE CABLE before spending a week trying to open
a box you are not qualified to look inside of!

WHAT were you expecting to find, a soldered cable connection
/inside a sealed enclosure/ which just /decided/ to come
undone for no reason whatsoever?

And, BTW - an e-meter (q.v.) CAN be used to test cables, as I
realized after posting. But I waited, hoping for an
entertaining reply - and I was NOT disappointed! ;-)

I am not a professional electronics repairperson.


Neither am I.

I don't maintain a repair shop, nor solicit repairs.


Neither do I.

This is why I own no XLR connectors: normally I have absolutely no
need for such things. I have no sound equipment, microphones, etc.


I used to sing (using the term loosely) and play guitar
(etc.) in bands, so I have a ton of XLR (and other)
connectors and cables, etc. I understand not everyone has
such items on site.


Good. Sound reinforcement was never my responsibility even when I was in
this band.

This one just landed in my lap. I used to be in a
band, the leader of which just recently died, and when we
tried to use this amp at a gig, it failed.


It's not a bad idea to test other people's
instruments/equipment before using them, let alone WHEN DOING
A GIG.


The amp was not essential to the gig; we just wanted to use it to make
announcements during the performance, as it was also a memorial to the
founder of the band who had just died a week before. Since we were
playing in a relatively small room, we make do without.

And there were NO other cables on the stage at the time, huh?


Nope. We're an acoustic band, generally play without any sound
reinforcement at all.

I offered to diagnose it and determine what was wrong with
it.


Hmm. So you ALSO used to be in a band, and you don't have a
single XLR cable in the house?


Nope. You see a problem with that?

Hmm. What kind of band?


Eastern European and Balkan folk and popular (from a previous century)
music. Mostly totally obsolete music that most people haven't heard and
don't care about.

You, sir, are a gentleman and a scholar. Sure enough,
removing the nut from the phone jack allowed the whole unit

blade betwixt the case and chassis to start it).

WHAT? You did NOT do that when you removed all the screws? I
have not been reading the thread carefully ever since you
ignored my request for a photograph, but DUUH!

The amp appears to be fine; there's either a problem with
the XLR mike input jack, or with the mike cable we were
using. (Can't test because I have no XLR plugs.)

WHERE are you (as in, forest, garage with NO tools, an audio
shop run by Scientologists who believe the e-meter is the only
piece of electronic test equipment anyone needs) ????????

SIGH.

BTW, I have learned over the last 4 decades that it's ALWAYS the
cable (and if it's not, you **still** test any cables FIRST
before you do ANYTHING, including attempting to open an audio
box [when you should let your friends open your canned food for
you] let alone flooding an NG with clueless posts for a week),
and /had/ you posted like a person with a clue, I would have
told you to try another cable - I know you don't have one, BUY
one!

In the world of professional audio, it`s hardly ever the cable!


That depends on the quality of the materials and who made them.

Aside

That's a kind of music which is becoming very popular here in the UK, my
own home town boasts three bands playing such music. I rather enjoy it
myself.

If it makes you happy to think so. I've seen some real crap on the
market that was called 'professional quality'. BTW, I owned a
commercial sound business for about 15 years. I also saw equipment &
cabling that was 20 years old and still working fine. I see more and
more crap being made overseas that claim to be high quality or
professional quality that will be lucky to not be in a landfill in a

There you go then. You are confusing crap chinese, prepacked cables with
the words 'Professional' on the packet, for cables which are hand made
using the finest quality cable and connectors. There is very little 'on
the market' that is anywhere near professional quality. Most pro
companies either build their own cabling or have it made by companies
specialising in producing cabling for industry use. When your livelihood
depends on performance, you don't use 'Monster' cables!

In my forty some years experience of working in professional audio, I
have found that it's very rare for a properly made cable to fail without
outside intervention.

I feel stupid for not suggesting removing the nuts on the phone jacks.
I've seen this done sooooo many times.


Oh, so I guess that means I'm *not* a total retard, eh? Thanks for that.

Don't assume anything. I like medieval folk music as much as I
like The Sex Pistols /and/ The Carpenters. I do NOT care for
acoustic-guitar-based "folk songs" played by Californians, but a
lot of European folk music, Irish especially, is really cool.
/And/ Eastern-Eur.

Exactly. Which is the way we prefer it; we worry about our set lists and

And sometimes ones that are not visible. Just this week, I had a Sony
sort-of-portable thing on the bench. I took out every last obvious screw,
and no movement of the case halves at all. Then I discovered that the
speaker baffle was removable, and when removed, found two more screws behind
rubber bungs, When these were out, the case halves moved, but would still
not split. The final thing holding it together was the fact that the volume
pot was part of a board that remained in the rear case half, so its nut had
to come off. This fooled me for a few minutes, because I was expecting that
the control was part of the front board, and would come away with the front.
