Rank Bush Murphy: ColourVision Principles
For quite some time I've been searching for the RBM training manual, incomplete ones have turned up over the years but never a whole one with the binder, that is until now. An article for your pleasure https://www.radios-tv.co.uk/rank-bush-murphy-colourvision/ the full manual will appear in the data library in due course.
Excellent! Will MP3's of the LP's be available to?
