My thanks thanks go to Rich (Marconi MPT4) who has kindly provided some very rare information pertaining to the 20AX CRT system. This appears to have been part of a marketing drive “Mullard make The Great Leap Forward” by Mullard Components in the 70s. Find below the plates (click image for a much lager image).
I hope you find this rare article interesting.
Once again my thanks thanks go to Rich (Marconi MPT4) who has kindly provided this rare information.
