What kind of component is this?

Can't find anything via Google.  Too many pins to be an inductor, unless it has a bunch of taps for some reason.





FWIW, it's from an older (early 80s?) MIJ Casio adding machine that I picked up at Goodwill for a few bucks to see if there was anything to rat f*** inside.  Not much with any audio use.  I was really bored that day.  ;D

It is a many-tap/winding inductor-- a transformer. Used here to convert a single DC voltage, through oscillator and transformer, to make different DC voltages.

If it is still "alive", measure the DC at the far end of the nearby diodes. You may be shocked. Especially if this powered a VFD display... could be a small amount of +100V in there.

Thanks, Paul, I figured you would know.  Any point in saving it?  The display is thrown away, but maybe was a VFD, it was in evacuated glass.  No shocks, probably hasn't been powered up in years.

I second that, inductor. I used to work for a place making those stupid things.

If the inductance values are in a good range you might be able to use it in an Ampeg style tone stack with switchable ranges, might have to tweak other component values to suit, but could be useful for audio.

Switcher inductors are rarely anything like values we can use in audio.

I vote "trash".

Yep, me too.  It would have to be something pretty special to desolder all those pins!
