I just got a used monitor.
I can't find any markings that would hint at what manufacturer it's from. (It's a vertical mount monitor, and the tube has Popeye burn-in, so that tells me the tube was swapped, and therefore the information sticker on the tube is also irrelevant).
The closest thing to markings on the board are the letters 'DIP'.
So anyways, the monitor works but has waviness to it. I have not inspected beyond a cursory glance, but one thing that I immediately noticed is there is this "coil" thing on the bottom circuit board that seems to be unravelling. (It's loose enough that it wobbles when the monitor is moved).
The coil is made of reddish wire. What is this part called? And what role does it play?
