Recapping a Macintosh Quadra 840AV

[@jackjack1819]

Hello, thank for the guide, I need to recap a 840av and didn't know what capacitors to use. But I've question: it would not be better to use higher voltage capacitors like 20 or 24V?

Hello BC Fans, I need your help to identify the IC part number located at U9 on my 840AV logic board. I recently purchased this 840 from eBay as not working and I started removing the leaky SMT electrolytic capacitors. I discovered that the IC at location U9 is missing. Bomarc schematics appear to have it as part of the analog sound circuit for the headphone output. Thanks.

Hum, you mentioned a maximum number of computers before your partner leaves you. Do you know how many that is? Asking for a friend...
