This is the original "numbers matching" monitor for my Missile Command upright, and it's been in storage for the past 15 years (I've been using a Happ Vision Pro in my Missile Command for the past 15 years). Recently I decided I wanted to put the original monitor back in my cabinet, so I replaced all of the electrolytic capacitors (one of the larger ones was visibly bad), put it in the cabinet, and powered it on for the first time in 15 years.
The picture looks great. I actually can't tell the difference between it and my Happ Vision Pro (which is still like new because it has very low hours since I bought it new in 2010) in terms of sharpness and colors, but every time I turn it on there's discoloration in the lower corners of the screen (visible in the yellow ground of the Missile Command playfield), especially the lower left corner. The discoloration gradually goes away during the first few minutes that it's on and then it stays normal looking for as long as it remains on. The 2-position connector for the degaussing circuit is definitely plugged into the chassis and seated all the way.
Also, I'd like to move the raster a little to the right, but that 3-position jumper wire has no effect that I can see. The wire was plugged onto the far right terminal that's labeled "left," so I moved it to the center terminal, which did nothing, and then I moved it to the far left terminal, which also did nothing.
