Hi to all,
Sept 3rd: Noriyoshi has resumed work on restoration of the Chromatron.
Picture is now in focus and fully covers screen.
Still some work needed on the color decoder - see photos.

I have acquired a 1967 Japanese book where there are the schematics of the Sony 19C-90 Chromatron, essentially the same model but in a different cabinet, this one is a floor-standing model.
See the full resolution scans on Marshall's site (Thanks! for posting them).
Scanned as 4 pages to not wreck the book.
Located approx. middle of the very long page.
