    Good work, Shawn. Glad you got it fixed finally.

    G08 HV question - low voltage, good picture?

    I've lost count how many times I've now repaired the G08 in @CarrieZ 's Space Fury. The one good thing about it is that it introduced me to vector monitor repair by throwing me into the fire. I think this is the 4th or 5th time I've fixed this thing. Each time it's been something different and...

    G07 missing top half of picture

    And yet he would regularly proclaim that Peter's caps were absolute crap. Oh, the irony.

    Super Hang on monitor replacement

    Yep. Mine had a shelf mount K7000 in it. Here's a couple photos of mine when I was in the process of restoring it.

    G07 weirdness

    You can also rotate the yoke a little too. It'll obviously affect the orientation of the entire image, including the top, but you may find a happy compromise. (I've used magnets on the tube to correct things like this before, but that's a can of worms of it's own and requires a ton of...

    G07 weirdness

    Other than bringing your vertical size down a tiny amount and possibly centering it a little more vertically left, I can't make out what the issue is.

    G07 weirdness

    Few questions: 1) Is this an original G07 tube & yoke? 2) Is the crookedness on the top and bottom? If so, that's just a matter of rotating the yoke. 3) To me, the image looks slightly bowed at the top and bottom. Is this correct?

    G07 weirdness

    You should be able to get at least a good inch or so of adjustment out of the coil. If not, I'd check the coil and area surrounding it for bad/cold solder, and look over the coil too. It's possible it's cracked and/or broken. People tend to downplay how much adjustment you can get out of a good...

    G07 weirdness

    Only if you can't reduce the horizontal size enough with the coil. If you aren't able to reduce it to the point where there is black on both sides, you may have to change the value of cap. Vertical size shouldn't affect anything.

    G07 weirdness

    H. freq adjustment should get that curl out. Like @tron guy said, you may have to compromise on the centering a little. Usually, I'll reduce the size a bit, then adjust the curl out and get the image nice and square. Then center the position as best as possible without reintroducing curl. That's...

    M5000 B/W Monitor - Positioning?

    Miss that place, back when it was entirely pitch black (save for the worker booth) with no lighting but the glow of the monitors. Found this old pic. Guessing this was taken late 70s. I see MusicLand and Stereo 1, so definitely pre Sam Goody era. Wish there were more old documented photos of...

    M5000 B/W Monitor - Positioning?

    Gorgeous. I'd love to find a nice bezel like that. I've thought about restoring/restenciling the control panel, which wouldn't be too hard, but there's no real point if the bezel isn't nice as well. Oh well. For now, it's vintage late 70s/early 80s patina!

    M5000 B/W Monitor - Positioning?

    Haha well...my OCD got the better of me. Digging through the manual, I discovered that L3 is the horizontal linearity coil, and using my magnet "trick", I was able to get it much much better. Two disc style magnets on top of the coil, did the trick.

    M5000 B/W Monitor - Positioning?

    That did the trick. After a good 90 minutes of finesse and tweaking, I got the picture dialed in to where I like it. Thanks @cwilkson for the tip! The only thing that could be better is the horizontal linearity. The right side of the image is slightly wider than the left. (If you look at the...

    M5000 B/W Monitor - Positioning?

    Oh sweet. I did see the rings you're referring to but had no idea what they were for. I'll have to give it a go. Thanks!

    M5000 B/W Monitor - Positioning?

    I was just doing some final adjustments & tweaks to the M5000 monitor in @CarrieZ's Exidy Circus. Picture looks great, but I can't quite get the image centered horizontally. Does anyone know if there's a way to adjust the horizontal position without adjusting the H.hold/Osc coil? I read through...

    G07 lines on screen(solved), right side too narrow

    Came across this old thread and wanted to bump it to say that I have also seen this issue. One of the G07s that @CarrieZ has, does this. Can't remember which. @tron guy did you ever solve this mystery? EDIT. I just remembered, it's the G07 in her Ms. Pac/Bitkit cabinet. Rebuilt G07, works and...

    Tech Help Needed -- K4900 Slight Horizontal "Pin Cushion"

    😆 hah - yeah it's definitely a painstaking process of trial & error (that I usually spend hours on), but it does work. It always depends on the game and whether or not it's worth it. Many games don't benefit from it because you can just adjust it out. But if it's a game that has text or other...

    Tech Help Needed -- K4900 Slight Horizontal "Pin Cushion"

    I've seen this on a few 4900s, both in a vertical mount and horizontal. It seems to be a fairly common characteristic with one side (namely the horizontal right side). The only way to correct that (that I know of) is to use magnets on the tube itself -- if you're willing to spend a chunk of time...

    Simple Fix for G08 Partial Deflection /Collapse

    I left it in the cabinet when removing the monitor. Thanks though!
