Help. I have an issue 2 board ? Mac (Late 85), and after a recent homespun
512k upgrade, I have apparently lost the PSU.

I have recently heard of a problem with CR1 (?), and have a few questions
based on this information:

   1. Is this accurate, although the part mentioned is available cheaply, will
      it solve the problem, or just postpone it ?

   2. Is this relevant on an English PSU ?

   3. Are there any other problems likely to be coming my way ? ( To the
      best of my knowledge the upgrade was a pretty good job, carried out
      by an engineer here.)

   4. And here's hoping, Does anybody have the relevant part of the circuit
      diagram, so that the engineer can at least have a look at what has gone
      wrong.

My mother waits on your every word...

Thanks in advance

                     Adrian Hill.
