    G07 Hsize too small

    A hp probe shows 20kV under the anode cap, same as another G07 anode of a chassis that is working well. Here are pics in the game. (There is an unusual couple of fuses on the side rather than on the board.) The width coil looks like it has an odd loop and has some goop on it, and certainly...

    WTB: Space Invaders cocktail parts : control panels , coin mech, etc

    Did you find a glass top? I'm also looking for one. I see them for Midway cocktails, but not Taito.

    G07 Hsize too small

    I started with a new cap kit it last month, fully believing/hoping that would fix it... No luck. I am borrowing a high voltage probe and will test the flyback voltage and stability next.

    G07 Hsize too small

    First: thanks very much for the offer, so kind of you, we are fortunate to have your invaluable expertise, time, and willingness to help. Second: No, the flyback was not changed in the last 10 years I've owned this. But, I do see the width coil plastic casing is cracked and sort of loose to the...

    G07 Hsize too small

    Just FYI. I tried and replaced c515 from the original old .53uF to a new .47uF. After the painful process, I can’t say that I see any difference… I didn’t mind trying, just in case, but I don’t think I want to repeat this process iteratively with smaller values…

    G07 Hsize too small

    I swear it’s been slowly getting worse over the years. But I can’t recall a specific event or day when it got significantly worse.

    G07 Hsize too small

    My cocktail ms pac man h-size seems to be shrinking…. The horizontal coil fails to increase it. It’s an electrohome G07. I checked a B+ at 120VDC. I recapped it. No change. I cranked up brightness to show on the picture how far it is from the top and bottom edge. I saw in another thread the...

    I’ll take the Galaga cocktail CPO if you still have them. Thanks.

    K4600 Missing Blue

    Sort-of-solved... After changing a variable resistor, adding solder on a few spots and all header pins, and double-checking everything I could in the red path (comparing some values to blue & green), I still found nothing wrong yet no red color. I finally swapped tubes and that did it. So in my...

    ANOTHER CGA to VGA BOARD QUESTION

    So this may be a dumb suggestion, but has anyone tried an old VGA CRT monitor instead of LCD? 19-inch ones are probably rare, but I there are still a lot of 17in out there... Would a 17-inch old PC VGA CRT monitor look ok in a Galaga? too weird? maybe too small?

    Yes, he rocks! I appreciate his knowledge and admire his beautiful work.

    Garbled Galaga

    Yep, checked power supply and voltages. I also swapped another working Galaga board that works in that cab. So, I'm now focusing on bad contacts on the PCB... but I don't want to go crazy on the poor old board either.

    Garbled Galaga

    I made some progress. Cleaning and resetting the z80 chips got rid of the watchdog problem. It no longer reboots, it fairly quickly stops on this screen. I’m worried about doing more harm by soldering all these small resistor arrays. Should I try anything else first?

    Anyone used an LED tube to swap out a fluoro?

    When my ballast died, I found "2FT T8 LED Tube Light", e.g. on amazon; they are cheap and so easy to wire with no ballast. There are even some Color Tunable ones (3000K/3500K/4000K/5000K/6500K). I've used them with pinball backglasses, and I love the results.
