My thanks to those who replied to my posting on the subject of dimming
SM124 white characters on black background;  It appears lots of people
have had this problem but no one knows the solution.  Suprisingly,  Atari
UK claim to know nothing of this 'feature' of their monitor.  The
phenomenon seems limited to 'heavy' SM124 models that use a large mains
transformer,  later versions using a light switched mode PSU are not
affected,  neither are SM125 monitors.  A service man (Charles)
fom Silica shop seemed more helpful,  and said he would investigate the
problem if he could reproduce it on his SM124.  Since the Germans seem
to be the best ST hardware hackers around perhaps a German reader of
this BBS may have read of this and be able to shed light on the topic.
