SE/30 lost a chip Q3, what is it's replacement?
Posted by: Lord Refa on 2024-08-29 12:41:58
Was working on recapping an SE/30 and the far left side cap had created a little bit of corrosion round it's leads and a nearby part noted as Q3, looks like a tiny voltage regulator. It just fell off when cleaning with a q-tip, and now I need a replacement. Pad took a while to clean up, but they are ready to receive a new part. I believe teh part was marked "1A3" which doesn't tell a lot. Any ideas for a replacement? Thanks.

When components "just fall off" it suggests a bigger problem of corrosion , be it from electrolite or acid

you might want to take a decent picture of your logic board and post it here

did the battery leak ?
