Default Keepiing old dynamic mics working properly

A number of my older dynamic mics have had the foam inside them basically
turn into dirt.

What do you do when this happens and the mics aren't even made anymore? Buy
a replacement for another mic that is maybe sort of close in size and try to
cut it to fit? Just get some open cell foam and have at it or what? Where
would I get open cell foam that would be appropriate for this?

A second somewhat related question about my Beyer 260... This mic is very
tricky to get inside, is there foam inside this mic that has probably
disintegrated like my other mics. I know the 260 is a dark sounding mic but
this one is really dark sounding.

First clean up the mess. Then see what it sounds like without the foam.
If it sounds OK, leave it that way and just don't spit in it.
Otherwise, find some thin not very dense foam and put a piece inside so
that it covers the holes. Try a shop that sells upholstery materials.

Oh, you mean it doesn't have any high end? Yeah, they get that way
after a while. You need to get the ribbon replaced. It's outrageously
expensive from Beyer. For about $125, Stephen Sank has replaced the
ribbons in two of mine (as well as several other 260s) with a new
ribbon made from RCA 77DX stock material. It's somewhat "darker" than
with a new Beyer ribbon but it sounds quite a bit like an RCA 77DX. Not
a bad thing for a mic that you don't use because it doesn't work right,
but at least one person here had it done, didn't care for it, and
coughed up the bucks for a genuine Beyer repair (which I believe
nowadays is replacement of the entire "motor" assembly.

You can get open-cell foam from an acoustical supplier that will be good
for the job. It's much more open than the stuff used for absorption. But
you can always cut up some windscreens if you have to.

The ribbon is bad. If there's a lot of low end no top end, it needs
a new ribbon. Be sure to ask for the original parts back.

Yep, If you don't have trouble with popping your P's most mics sound better
without the foam anyway.

Some motherboard boxes come with a fairly porous sheet of foam in
them.

Just out of curiosity ... what do you want the old parts for? Just in case
it doesn't fix the problem, you then have spares?


Because they replace basically everything inside as one module. Which
means you get back the original transformer.

That transformer is very useful, if only to install into an M-260.80 to
turn it into an original M-260 which has more low end.
