GUYS,

I can't believe how helpful you all are and I thank you all for your advice.  I will endeavour to try the things you have suggested, might call my sparky (brother) who is likely to understand some of this stuff better than me.
I'll let you know what happened for your own curiosity as soon as I get a chance to do it.

I love my MM, got to be one of the best pinnies I've ever played!
