I’ve probably said this before, but I always admired Philips’ ability to produce every part for their products in house.
I used to work in the factory where Philips made those CRTs.
EVERYTHING, literally EVERYTHING could be sourced in house back then. It was glorious.
We had a great T&M department that supplied all of our testgear. Scopes, DMM, pulse gens, hell, even isolation trannies. Everything started with "PM...".
Caps, resistors, ICs, trannies - you name it - we made it.
And all the machinery to make, calibrate, measure and test the CRTs was made in Eindhoven or our in-house tooling shop by our own people. I guess less than 10% was bought parts.
And you could get any drawing, service manual, mechanical drawing you wanted. There was an office with an old russian one-eyed guy. You'd pass him a slip of paper with the drawing number and he'd be like:
"Chom' back in half hour, da?"
He pull up a microfiche from the archive and then somehow transferred that onto A1 paper. There was a huge printing machine with a big drum where the sheet would wrap around. It rotated for some time and the drawing was printed. Don't know what type of printer that was, if anyone knows, please let me know.
He'd then put the sheet on a large table, reinforce the edged with thick transparent tape and gave it the DIN824 fold. See:

"Here, is finish! Dasvidaniya!"
God, i miss those days!
