I would like to see a pic of the rear which i can't find.
I often have to uncover hidden screws in things.
I also have to do alot of prying on things.

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.

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.

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. :)

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".

Because an average remote gets dropped at least a few times a
week (my statistics), and is occasionally thrown at various
inanimate objects and assorted life forms.

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!.

Ha! I was just about to come in with exactly the same observation, and you
beat me to it ! 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 ?

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.

Heh; I'm totally not familiar with this device (almost old enough to be,
though), so when reading this I had visions of splitting open a 14-pin
DIP with a chisel, fixing it and gluing it back together.

Now *that* would be some repair.

Respect what?
According to your profile you are an asshole no matter which newsgroup
you crap in.
Dave sparkyguy442 (the yahoo place) asked a simple question, and it
is possible that someone in this group can help him. That is (by the
way) what this group is about. Helping each other, NOT having to skip
past your self worshiping drooling drivel. Crawl back under your slimy
rock. Nobody will miss you. Trust me on this. This nation was built
on lab rats who kept on asking questions until answers were
discovered. What nation do you germinate in?

Make everyone happy and killfile the troll. All you're doing is playing into

Has the cable company been in your area lately? Are you using a legal
box? are you sure your friendly cable company didn't install a charge
pump device on your line to burn out your illegal box ?

Inquiring/creative Minds would like to know..

Yes, it's a legal box. I bought it used on ebay from a guy who had
moved to a different city and he'd switched to a different cable
company. When he left, he had the cable company de-activate the box
and when I connected it to the TV I had to call the cable company to
activate it before it would work. I think the cable company would
know if the box was legal or not...

Is your mind satisfied now?

FS: Rare Texas Instruments TIL306 Numeric Display w/Logic NOS

This is a solid state display used in some shortwave communication transceivers and commercial broadcast transmitters as front panel status, frequency and error code readouts. THESE DISPLAYS WERE DISCONTINUED IN 1992 AND ONLY A HANDFUL OF NEW OLD STOCK EXIST TODAY. Some dealer in Europe is selling these for $330 each.

I'm selling for $30 each + $3 shipping:

For price reference on these hard to find display chips:

Other suppliers are selling this display for a Buy Now Price of: £212.99 US$330.13 Euro 266.24

I'm selling mine for 1/10th the price, priced to move, not sit in an auction house waiting for top dollar.
