Default Cracking open a Galaxy Audio PA amp


"David Nebenzahl" wrote in message

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.

Do the control knobs on the front come off to reveal spindle nuts?
