    Can I use a 25" K7000 chassis on a 25" U2000 tube & yoke?

    Would a 25” K7000 chassis work in a tube/yoke/rings where a U5000 chassis was installed? I understand that I would need to add an isolation transformer. Thanks

    P719-I U5000 neck board, lifted traces

    Yeah, the wires are fine. If I bend the board slightly, red comes back until I let go. It’s got to be a bad connection somewhere else. I just can’t figure out where.

    P719-I U5000 neck board, lifted traces

    So I ran jumpers and retouched a lot of joints but unfortunately I can’t get red to stay steady unless I kind of press on the neck board from the edges. Blue and green are fine. It’s a broken trace somewhere but I can’t find it. I’ve attached pictures for your viewing. Hopefully someone can...

    P719-I U5000 neck board, lifted traces

    Anyone know where I need to run the jumpers from/to on these lifted traces? Any help is greatly appreciated. Colors keep going in & out. If I press on the neckboard, the colors are fine until I let go. I'm guessing that's the reason.

    WGM2775-U0TS50K Question

    Is this a cga or medium resolution chassis? I’m hoping that it’s cga or if it’s not, is there a switch on the chassis to make it so? Thanks for help

    Need some help

    The attached image is what I’m supposed to be getting. I ordered what was installed which was a 4.7uf. Perhaps I need to order the 6.8uf. I don’t understand the ‘high frequency’ reference. Can you send me a link of what you have? Or if anyone else can chime in.

    The stuff I ordered from digikey popped within a few hours. Need some high frequency stuff but don’t know which to order. Any help is appreciated

    Need some help

    Can someone point me to a link or two where I can order a ‘high frequency’ bi-polar 4.7uf or 5.6uf or 6.8uf 50V cap. Apparently a ‘regular’ bi-polar won’t do the trick. Any help is much appreciated.

    4600 Waves in Qbert Cab, not in other cab

    Isolation transformers too close to the monitor will also cause this issue. It's happened to me.
