Did Color Classic use any tantalum capacitor?

[9166188]

Got a little fellow dropped out as I pulled the CC motherboard out from its body.  It is a yellow tantalum capacitor of 33u 25V.

Since I haven't recapped anything, all components are original.  I thought it came out from the motherboard.  But my search was futile.   Nothing seems missing in the motherboard nor the analog board visually.

WHERE could that little fellow come from?  I have NOT used any tantalum capacitor myself.  It definitely came out of the CC body.

Quick answer from top of my head - yes they did it was only a couple.

Indeed it does have a few very small ones.  But so far can't find anywhere to fit a 33u 25V.

I don't believe it has tantalums unless it is the one on the top right. see http://www.maccaps.com/MacCaps/Capacitor_Reference/Entries/1993/2/10_Macintosh_Color_Classic.html

Thanks for looking into this.  The highlighted component (w/ silver color) is intact on my CC mb. 

I had search capacity list of CC before, but none of them uses 33u 25V.  The cap may not come from the mb or even the analog board but other parts of the CC.  So, still a mystery to me.

I do see a yellow tantalum cap here, https://www.thinkclassic.org/viewtopic.php?id=202&p=2 but please note that I did not read the entire thread. If you scroll down you will eventually find post #44 where three images of the MLB have been posted, the third down has capacitor (C1) and it is a yellow tantalum cap. I don't know if that is a Mystic CC so that might be not be your MLB but it might be hopeful.

Check your board for anything labeled C1, C2, C3 etc as that can also help you find a missing cap.

Of course, the other possibility explains the yellow cap shown on post #44 might be that it had been changed.

Thanks a lot for spotting that!  Unfortunately, my board has C1 intact.  I now suspect that the orphan capacitor might drop out of a vertical board at the very front which has a cable to connect the floppy drive.   It is very deep inside.  I'll probably need to disassemble the major parts in order to examine it.  I will need to take a deep breathe to do it.
