A little Surprising, CT100 Fans

I had a go at replacing the pot with a standard type, which actually still had the same part number called out in the Sams for this set but with a much smaller element (think volume control). I can now confirm that a modern Clarostat A47-5MEG-S will arc right accross all the terminals with focus voltage applied to it, so it's back to the drawing board.
