68kMLA Supporter elemenoh Posted January 4 68kMLA Supporter Report Share Posted January 4 I'm in the middle of restoring a Mac XL. I didn't see a capacitor map online for these. So here is one in case its helpful to others. Pardon the cob web filled PSU. I'll be cleaning that In addition to these there are some axial electrolytic caps on the CPU / IO boards too. Those are: (19x) 10uF 16v 85º 12mm L x 5mm D (1x) 470uF 6.3v 85º 17mm L x 8mm D (1x) 2.2uF 50v 85º 13mm L x 6mm D (1x) 47uF 16v 85º 14mm L x 6MM D Quote Link to post Share on other sites
stepleton Posted January 5 Report Share Posted January 5 Nice photos! It may be worth pointing out that this is the (superior) 1.8A PSU as found in the Lisa 2/10. The Lisa 1 and 2/5 use the 1.2A PSU, a completely different unit with different components. Quote Link to post Share on other sites

I've actually found the 1.2a earlier version to be more reliable than the 1.8a PSU. I don't recall their common failure points but the 1.8a always had issues. In any case, this is a very useful thread for those looking to recap. Thanks @elemenoh! Quote Link to post Share on other sites

68kMLA Supporter elemenoh Posted January 16 Author 68kMLA Supporter Report Share Posted January 16 The original post doesn't cover C7 which is a .33uF 250v film cap. I'll add it with dimensions an lead spacing to an updated graphic soon. In the mean time, here's a photo of my recapped PSU. With a Hakko pump it was pretty painless to do.

Well, as if to teach me a funny lesson, my 1.8A DataPower PSU has just gone kaput --- it shuts itself off immediately after power-on. I have a rather noisy 1.2A PSU that I can use as a backup for now, but I'll want to get that 1.8A unit working again so that I can power my Widget drives. (I have an external PSU that I can use for Widgets, but that's mainly for maintenance work on the bench.) Quote Link to post Share on other sites
