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! ;-)

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.

When you loose neg bias on audio output bottles and a hole is burnt through
the anode plate and up to the point the the glass melts and vacuum is lost ,
is that plasma cutting?

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 ... :-)

IME diamond saws are a more readily available and economical alternative.
This is one of the major changes in tooling of this millennium - industrial
diamonds are now so inexpensive that tools that effectively employ them are
readily available in most big-box home improvement stores. That all said,
this product seems to be composed of materials that are too soft and too
temperature sensitive for effective cutting by diamond-tipped tools or
plasma cutters.

A diamond saw? Save that to remodel your bathroom.
