Step1, if you get your new HDD soon, pics would be appreciated.

Jon, I am bummed, I made sure to ohm out the phase link and super tweeter before I spent the money on the 8's and 10's and they all read good.  The coils must be good but detached like Step1 mentioned.  I sure hope they are easy to disassemble.

If you decide to take the dome mids apart, it's a pretty easy and self-evident thing. There's 3 plastic tabs that click into place behind the metal rim of the driver frame. They're attached to the diaphragm/voice coil assembly. Just pop back those three tabs and the whole diaphragm/voice coil assembly lifts right off.

There's a small difference in sound between the earlier, clear domes, and the later, fabric domes. With the given crossover network in the MS150, the later, fabric domes sound ever-so-slightly more laid-back and pleasing. The difference is slight, and I mean slight. If you can find a good set of those, they'll work too, IMO. Won't be original, but it won't be way off either.

Awesome, sounds easy.  More bad news...the water heater in my house went out today.  Spent $600 so far and haven't even started putting it in yet...ouch!

It may be a few days before I can try taking those apart, I'm swamped.

Thanks for the tips, I'll keep you posted.

Kind of good news as fingers crossed I might have new drive at end of week but then I have to re-install windows and get everything up and running once more... Might just beat you with those photos :)

Good news everyone.  Finally got a chance to take those phase links apart and the coil was sitting by itself when I took the dome off.  Unfortunately the magnet wires broke off at the terminal but that shouldn't be a huge deal.  I only opened one of them and will bring them to the speaker repair place to see if they can fix them.  It would be tough getting that coil centered in the gap since they won't be able to use shims or anything like woofers can use.  The odd thing is that I saw no evidence of any glue ever being used, no residue or anything. 

I will keep everyone posted, getting excited again even though this means more money :)

That's good to hear :) Yes I was very careful when centering but it can be done on the diaphram - You can see an edge that the coil sticks too but get this dead right, make sure the coil isn't mis-shapen. Hope the repairers do a good job for you!

I haven't heard anything from the shop about the phase links yet.  However, yesterday I spent time re-mounting the 8's and feel a lot better now.  I ended up cutting the tube like Jon suggested (I'm still curious how B&O mounted these originally without cutting the tube).  The metal brackets now extend a little into the tube and the rubber pieces are pressed firmly on the frame of the driver.  My only concern is since the tube was cut in 4 spots for the brackets, that it is no longer totally sealed.  I used hot glue and tried to fill the voids around the brackets to seal it the best I could.  When the drivers need to be refoamed again in 15 years or so, hopefully it won't be a huge pain to get the glue off.  Would you be concerned about having a few tiny areas that aren't completely sealed off?

Nope, not in this situation.

Another update...I replaced the European connectors with gold plated binding posts and ran new wire from those to the crossover (the original wire seemed very undersized).

Finally got a call from the repair shop and more bad news...One of the phase links had a bad voice coil (wasn't blown but the wires were coming undone off the former).  The other one he re-assembled but it buzzes.

Where do I go from here?  Is there a replacement driver from partsexpress that would fit and sound similar?
