Hi all,
I'm not up with the theory on the Magister system or, indeed, that thing 'electricity'.
I'm glad there appears to be a possible solution for failing or failed units.
From a historical point of view, this is one of the curiosities.
I would particularly like to thank Moderator Gadge for that extraordinary research
and summary of the issues, and I hope Blue finds a suitable solution.
All very commendable.
