SE/30 Speaker Replacement

[Tempest]

I have an SE/30 with what I believe is a dead speaker in it. There's no internal sound, but I get sound just fine if I plug in speakers. I have a working speaker I pulled from another Mac, but I'm at a loss as to how to get at the SE/30 speaker. Do you go from the back or the front? If it's from the back, do you have to remove EVERYTHING to get to it? They really couldn't have put it in a more inconvenient spot...

I'm pretty sure you need to slide out the motherboard (disconnecting all cables), and just the metal bracket inside housing the floppy drive and hard disk to get to the speaker.

Do you have to crank up the external (powered?) speakers high to get sound? If so, it suggests a failing caps problem which should be fixed as otherwise the sound will one day fail completely.

Nope, I actually had to keep it low or they got really loud.

I looked at removing the big metal bracket thing, but there's one screw that I can't get to because it looks to be under the power supply (which is also a pain to get out).

Ok I just had a look at the SE/30 manual: http://www.macheaven.net/MH_Manuals/macintosh_se30.pdf

If you look at page 66 you can see that to get to the last screw on the right you have to remove the power supply and the analog board. I'm really not keen on removing the analog board because that involves touching the anode cap on the CRT (or at least the part of it that plugs into the analog board) and that scares the living crap out of me. I'm also afraid that even if I get this thing out I'll damage the CRT somehow (hitting the yoke or something).

The manual also says on page 67 that you have to cut the plastic that holds the speaker in to get it out. That's fine, but how do you get the new one to stay put? Glue? I assume the speaker I stole from my Macintosh II is the same and can be used to replace the bad one?

You can gently slide out the analog board of it's notches (remove ~ 2 screws on the outside) and not have to take the whole thing out; this will give you access to the elusive screw (hex bit, you'll need a long screwdriver handle to get to it)
