Someone on one of these groups suggested a very good service manual site,
but I never find it because the link to open the document is obscure.

The PSU is the worst I've seen that didn't already go bang!

Changed all the bulged electrolytics and ESR tested all the others - but I
think I got one mixed up putting it back. The service manual would be quite
handy.

Or I could just fire it up and see how loud the bang is....................

Thanks for any help.
