Hi Phil,

do you have a circuit plan of the PSU?
The 1.2 amp PSU circuit plan is available on the Internet- but the stronger 1.8 amp PSU plan is only available from John Woodall or James MacPhail- he has produced these plans.
You should find the plans on Ebay or : www.vintagemicros.com (John's homepage)

I can tell you which caps have to be (or should be) removed. It's easy for the 1.2 amp PSU- just tell me if you have the plan.

Helmut
