Amiga 1000 Power Supply repair?

[TCMSLP]

I was hoping this would include PSU schematics but sadly it just says "if volrages are incorrect, replace PSU" - but worth checking all the same:-

Several sites suggest A1000 PSU schematics have been available but all downloads fail.

This site offers a reconditioned A1000 PSU for $29: http://www.oldsoftware.com/Amiga.html

However, if it's an old fashioned linear PSU it should be quite easy to diagnose and fix.   The form factor makes me think it's a SMPS though?

Switched PSUs typically suffer from a few common modes of failure.  Without trying to teach you to suck eggs, I've found this guide to be very useful in the past:-

I have to admit though, the last SMPS I tried to diagnose I ended up simply replacing.

If you do make any progress I'm sure your experiences (positive or negative) would be useful to others.
