"David Nebenzahl" wrote in message .com... 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? -- 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.

Hi!
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. 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. William |

This product appears to be the pro-audio equivalent of most remote controls.
I'm sure most people in this group have noticed how remote controls are generally held together with screws /and/ near-unreleasable tabs. I've never understood why both are needed. |

Six screws attach the metal panel to the plastic cabinet. The plastic cabinet is ONE PIECE, totally seamless, covering the remaining 5 sides.

I've seen more than my share of remote controls that need tactical nuclear weapons to dismantle, so I feel /some/ sympathy for this poster. If the OP is still listening... It might be that you have to "pull like hell" on the front. It might be that there are no latches, and the panel is /so/ tight that it's stuck. You might also try removing the speaker (if there are external screws holding it) and poking around inside. |

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. Many years ago, I had to take apart a Philbrick K2-XA (those of you old enough to remember this op-amp will realize how long ago). I couldn't figure it out and called the factory. One of the engineers told me the plastic case came in two halves and they were glued together at the factory. The cases were so cheap that when a unit came back for repair the case was split with a chisel, and after the repair was complete a new case was glued on. |

I like to say I would rather be wrong because I express a carefully considered point of view, than right because I agree with everyone else. So on that basis, I'm on your side. I suspect that, as I said in the preceding post, something is badly stuck and won't come loose. By "stuck", I do /not/ mean "held in place with clips". I mean "jammed in some way". |

Quite a few of these powered speakers follow that general style of construction, and it's common for something like the self adhesive draught excluder foam strip that you fit around door and window frames, to be used to form an airtight seal between the ally casting and the heavy plastic case. It's not uncommon for this stuff to stick like a bitch when it's been clamped up in that joint for a few years. If there genuinely is just the six screws holding the front to the case, then likely as not, the answer is just going to be brute force. Is there even the tiniest gap that you could perhaps get something like a wide wood chisel into to see if you can spring the plastic away from the metal a little ? Arfa |

most of my life. Recently I have been feeling better, but that's another subject. Welcome to the club. I have a very morbid personality. The German Requiem -- especially "All flesh is as grass" -- is my idea of light, frothy music. The compensation is that I have a terrific sense of humor, which seems to go with chronic depression -- qv, Brahms and Lincoln. I would never try to talk someone out of their depression.
