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).

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.

Sheesh. You "shoulda" known enough to do that, at least. Good
grief.

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.

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 fuck (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.

Nah, all our humor comes from the UK: Monty Python, Dame Edna, Eddy
Izzard, Tracy Ullman, etc.

Ackshooly, I've been saying for years that there are two types of
Americans distinguishable by their taste for Brit humor. One one side we
have the PBS-type humor, exemplified by "Are You Being Served?" (which I
despise); on the other are those who like Benny Hill. I'm in the latter
camp myself. (Hey, what's better than total slapstick? Worked for
Chaplin ...)

More force is definitely not the answer (despite the many jokes here
about dynamite, angle grinders, etc.)

The key was removing the nut around a phone jack on the back of the
case, which you'd know if you read through the rest of the thread.

No, it's not, and you're misunderstanding the packaging here.

There's a diecast metal front panel which covers the entire front of the
unit, with a deeply set grille for the speaker. Six screws attach the
metal panel to the plastic cabinet.

The plastic cabinet is ONE PIECE, totally seamless, covering the
remaining 5 sides. So it's not a clamshell like most remotes or similarly
packaged electronics.


it most likely has a sealant between the front and plastic case to
prevent vibration at the seem, which is common with that type of
construction.. These things will stick like mild glue..

With the screws half way, wrap the unit in a soft wrap of some kind
like foam rubber so you don't scratch it, rest it on a pillow and use
something like a piece of wood to hit lightly against the screws that are
half way out.. The shock should push on the plastic behind and break
the bond!.

Yes.....Even if you were to crack the plastic, cracked plastic is a fairly

easy thing to fix, and/or live with. Consider cutting a large hole in the
back, which can later be covered with a glued- on piece of plastic, and used
as an inspection/access hole in the interim. ( I belong to the, "get a
bigger hammer" school of maintenance....:^)

As you probably know from reading my posts on other forums, David, I do my
emailing serially, and seldom have the time or inclination to, "Read the
rest of the thread." For one thing, I only get to email at all for a short
time each day, and I try, as far as I can, to be helpful during that short
time. I would think that you would be a little kinder to those of us who are
trying to help you with your problem.....You treat all of us like we are
just a bunch of smart asses, even though there are some of us who would
really like to help you.....If you would prefer, I can always put you in my
kill file, so I won't "waste your time" in the future.

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?


At least no one has suggested a Plsma Cutter! ;-)


Nah! "Angle grinder" as they always say over on uk.d-i-y


Angle grinders are for amateurs and wimps. It takes a real prow to
cut something open with a plasma cutter and still have anything left to
repair.



It's a standing joke on that group Michael. "Angle grinder" is the
'silly'
answer when anyone asks for instance how to dismantle a ceramic cartridge
shower valve to clean it, or anything referring to a 'delicate' job.
British
humour, and all that ...


And you still don't get American humor. ;-)



Wot ! You mean there is such a thing ... ? d:-}

Sure, but your senses have been dulled by a lifetime of exposure to
'British Humor' ;-)

The American equivalent is, "Get a bigger hammer".

If you need a bigger hammer, you ARE a redneck.

Even if you were to crack the plastic, cracked plastic
is a fairly easy thing to fix, and/or live with.

True, but cracking the case will sometimes crack the PC board. This happened
to me with an irreplaceable Toshiba remote.
