I don't and AKG doesn't either. I believe it's a single follower with a
transformer to tap voltage off. What's it doing?

Was dull and muffled. Got grille off and touched foam filter disk which
instantly turned into powder !

But the problem seems equally in the preamp, but haven't figured out how
to remove past the battery-chamber section yet.

Getting ~12V bias voltage out to cap from from P48 in.

Do you plan to replace the foam disk? I have a Shure SM58 that the same
thing happened to. The foam lining the grill ball had turned to a tarry
mess some years ago, but I recently found that the foam disk on top of
the capsule had also turned to dust. I carefully scraped it off but I'm
wondering if it's advisable to replace it.

Not replacing. Has a fine metal grille and substantial slip-on foam
pop-filter if required, but probably not to be used for vox anyway.

BTW foam didn't go the sticky way, but a dry fragile web that turned
straight into dry powdery dust.

If you remove the foam from the inside of an SM58, you get a lot more top
end. In fact, if you remove the whole ball completely, it sounds like an
SM-57.

On the other hand, if you remove the foam, you get a lot more wind noise
and the mike is a lot more prone to popping.

So, if you want an SM-58, replace the foam. If you really wanted an SM-57
but all you could get was an SM-58, take the foam out.

The foam from the inside of the ball turned to gum many years ago. I
scraped it out and have been using an external foam pop filter over the
outside. I recently discovered new replacement balls on Amazon for
cheap, so I did that. I just recently noticed that the foam disc on top
of the capsule had deteriorated, so I removed it. I probably won't
operate this mic without the ball filter, so I guess the diaphragm is
protected enough and I might as well leave it as is.

The foam inside the grill turned to a gummy mess a long time ago. The
foam disk over the diaphragm did kind of what yours did, got dry and
crumbly. Maybe two different types of foam?

All of that stuff is available pretty cheaply from Shure, although their
shipping makes it expensive if you only buy one thing at a time. But as
I pointed out, if you replace all the foam completely on an SM-58, you
get a mike that sounds like a new SM-58. And that's not always what you
want.

Of course it is, when you want to use it as a 57 you simply unscrew the
ball. Then you put it back on again for next time you want it for
vocals. Alternatively if you have 57's, slip on a foam sleeve when you
want them for vocals. You never have to worry about having the wrong one
anyway IMO. What I don't need is a 58 with a metal screen and no foam
though. Looks silly on instruments, and no good for vocals.
