NBA showtime or NFL blitz/NBA showtime combo in Gauntlet legacy cab So question will I be able to just switch out the pcb/hard drives in a gauntlet legacy cabinet or will the 49 way joysticks need an extra interface board to run the combo NFL blitz/NBA showtime boards? I have an opportunity...

Thanks I will finish out the caps and see how it goes. Seems I searched some and consensus was higher voltage caps were fine as long as the capacity was the same it should be good. Let me go find the rest of the 600's that I had not done and see if that does it. Thanks Marc

Progress finally thanks to Modessitt and his many posts over the years. I pulled u601 from the parts chassis I had obtained and I am now out of vertical collapse. I have replaced some of the caps but not all. Though it seems the picture is either high or offset towards the top as I have adjusted...

Ok pulled both d302 and d303 today and tested them out and both test good. I found a parts chassis locally to pull parts from but with both of those testing good out of the chassis I was wondering if there is something else to look at? I started replacing caps while I had it out but don't think...

I also found this one at Mouser. Does anyone know if this is a valid replacement for the RU-2? http://www.mouser.com/ProductDetail/Fairchild-Semiconductor/1N4937/?qs=sGAEpiMZZMutXGli8Ay4kC68PywQrfxCG2y6D5pGKw8%3d Says it is a 1N4937. Thanks

Ok called in some backup to help me out and per my dad the resistor is good though it is showing more resistance than what you said. Also from what we can tell with the diodes in place d302 is pretty much a dead short and d303 is open. I tested the legs of u601 and only one toned out to ground...

Ok I got the whole monitor so I was assuming the yoke was the correct one but I checked and it has a label of 9A3012-001 and the whole chassis has a sticker that says 27k7502. Now by open if you mean no resistance then yep r303 is shot. It also tones out to chassis ground. Marc

Thanks. For remote board, it is brand new but a p790 and from what I can tell is for a k7400 but from what I have read should be good enough for my initial testing of the monitor. I tried rolling/swapping the yellow/green and it just got worse. I tried testing d302/d303 but I really need to...

Just got me an untested k7500 monitor and chassis to get me back to med res in my gauntlet legendsand need some help. I am getting a horizontal line/lines across the center. Monitor and chassis look like it had little use. Fly back looked good as it had no ooze anywhere coming out of it. Does it...

What is the timeframe on when they will be ready?

Put me down for one. I checked and I think I am good as I saw the last board said Vegas 777 and it is a dedicated legend cabinet already. The reset header does not have anything attached on mine. Marc Davis

Sounds like you need to isolate if it is under play field or in the back box. Probably should do some jumper testing with the play field disconnected. When mine went haywire similar to that it ended up being a shorted diode in the lamp matrix that was the root cause. Took lots of testing to find...

Well I opened up mine to stare for a bit and if some of the GI comes on but not all then I would start the painful task of tracing those wires off the power board 3J8 connector though first you may want to make sure all those pins have the correct voltage. If you don't have the manual with...

Yes by GI I meant the general illumination circuits. I was lucky with the high speed I found and all of its issues ended up being either wiring or blow/shorted components under the playfield. So I did not have to work on boards or get any boards repaired/replaced and none of them were hacked...

Not sure what you are referencing by radar detector lights but all the others should be GI lights. So I would start with checking fuses but that is probably not it since some of the GI is working. It most likely is one of the GI wires or the GI connector on the power board. The connectors on the...
