PSU Schematics

[Stan Johnson]

Hello,

I would like to re-cap the PSUs in a few IIci systems and a Quadra. Is anyone aware of where the schematics for the following PSUs can be purchased or downloaded? If the schematics are not available, does anyone know who might own the copyrights now or perhaps reverse-engineered the PSUs to create schematics? The original companies appear to no longer be in business.

ASTEC AA15830
ASTEC AA16870
ASTEC AA15831
DELTA SMP-120EB

thanks for any information

Sorry I don't know of any schematics, but I do have a couple of capacitor lists here:

IIci power supply recap and component identification

I am recapping two different IIci power supplies, and am having trouble identifying some components. The first looks like a film capacitor. It is the rectangular shaped black component in the first photo with marking 2.0 uF 5%. In the second photo, there are many yellow rectangular components...

The lists are for the following ASTEC models: AA15830 and AA15831

thanks for your reply; the capacitor lists are good, but of course schematics would also be helpful for troubleshooting and might allow completely rebuilding the PSU from scratch with more modern components.
