I am trying to fix something (DSA) and it has this inside of it. I cannot recognize it.

It does not look like a battery that I know of

I cannot find the designator for it, the batteries are BT. this does not seem to have a BT nearby

Looks a little like a coin cell but not really.

Alex Eisenhut:
A tortured piezo buzzer maybe?

coppercone2:
hmm. it reminds me of a MOV for some reason but its position makes no sense

coppercone2:
the in circuit resistance is 8 ohms.

so that does sound like an audio thing ?

why is it trashed, the rest of the circuit is pristine, save for some crusty dip sockets

T3sl4co1l:
What's it wired to, AC power maybe?  Could be an NTC.  8 ohms might be healthy.  See if it drops when heated.

Haven't seen an uncoated one since... vintage TV sets maybe, I think?  Or maybe that all burned off somehow, yeech.
