    Modern supply that can handle radar scope’s -5v?

    yeah there's a lot of solder to clean up on those. my Red Tent multiple lifetimes ago didn't work at all when I got it and merely resoldering things in the power supply made it work again. and that version of me was a total novice, for posterity lol

    Modern supply that can handle radar scope’s -5v?

    yes, I learned the hard way that Nintendo games are extremely particular about presence of -5V. please forgive me KLOV for the atrocity of suggesting Arcadeshop Happ adapters lol

    need a new potentiometer for a rush 2049

    yeah I don't know when potentiometers became so ridiculously expensive and stayed that way, but the best advice I can offer is to not buy Amazon surplus stuff cause those will die rapidly. you need something that's called "long life", that's an important bit of terminology that got lost to the...

    Tron spinner rough rotation

    yes, I am there. to keep myself busy the last couple years I've been working on pinball more. my cervical spine doesn't appreciate it much though. PM me your number and we can talk more that way. (sorry for Tron spinner thread sabotage)

    Tron spinner rough rotation

    I worked at a place with a roller rink years ago. I used roller skate oil on trackball bearings to a Powerputt game I resurrected for them and subsequently carried that intelligence to where I work now. it made the Arkanoid spinners great. lol I wonder if it's similar to sewing machine oil?

    Tron spinner rough rotation

    sounds like you have to take it apart and clean/lubricate it. I don't even remember what they looked like, I can't offer any spiritual guidance there.

    Sense Circuit - Early Midway power supplies - Keep or bypass?

    running a sense power supply unloaded should just have the voltages higher I ran a medium power supply unloaded and had 5.15V, I just left it that way. it probably balances out to close to 5.0V to the chips with the game connected.

    Tron spinner rough rotation

    mechanically or it's not registering well? the spinner on the game at work a few years back went totally on the fritz, I don't remember if it didn't work at all or if it was just rough like you describe, but the header pins for the plug that connects to it were in dire need of resoldering

    Swapping a non-Makvision monitor into Big Buck Hunter Safari?

    you'll more than likely lose the sync signal through conversion, so that's probably not going to work. I learned this the hard way trying to stream NES games and Duck Hunt wouldn't work with my HDMI converers. also it's a PC-based game, it's a direct cable connection from VGA out to the...

    Sense Circuit - Early Midway power supplies - Keep or bypass?

    I'm progressively warming up to the idea of just giving up on life. or at least my existence at KLOV.

    Burger Time Cocktail Monitor wave issue

    I have big great news. it lives. but the wave persists. I had a theory that they just had the power supply transformer unplugged and that's actually what happened. after some analysis with the wiring diagram (my Super Pac-Man manual) I discovered Bally/Midway has their blues and browns...

    Burger Time Cocktail Monitor wave issue

    @1970 wanted the game reverted back to the medium power supply. I got the wires from Wire-Bot Friday and installed them (I made a near 1:1 duplicate of the suitcase AC plug) and I have no AC voltage coming out. I already pinged demogo and it looks like all the suitcase intelligence is for the...

    Utterly Baffled by a Sanyo 20EZ and Punch-Out's PT-1021B Power Transformer ...

    lower monitor and marquee light go to the outlets, upper monitor goes to the pigtail plug outlet gimmick the same power goes to both of the regular outlets unless it's like a load thing somehow preventing the top monitor from turning on? I don't know the anatomy of those things beyond what I...

    I told you what to do. that's how it was made. that's how it's supposed to be. if you damaged it then I don't know what to tell you.

    Offroad Challenge All lights on, no force feedback

    it looks like you have the cable plugged in backwards on the CPU board side if you look at the ribbon cable headers they will note where the 1/2 pins are, the red stripe end of the cables should be plugged in aligned to 1/2

    The pre holiday blues. PP.

    I don't know what that ram is but first plan of attack is pressing every socketed chip back in. with the boards separated and flat. try again and see if there's any change. it could be a socket problem or I don't know maybe a broken custom leg. (this is trivial to me and I don't care, for the...

    you may also want to take the chips out and plug them back in. I've never needed to do this but we exist in a strange timeline.
