Just did this mod and it did eliminate the hum for the most part, however the pot rotates counter-clockwise to increase volume, and clockwise to decrease. Is this normal?

I wasn't exactly sure if there are test points on that boardset somewhere other than just probing the ground and 5V legs on a 7xxx chip onboard which I haven't done, but at this point the power bricks and cables are swapped from one machine to the other, and I'm still ending up with the same...

I have 2 identical DK machines that have been running flawless for years, however DK#1 is acting up at the moment, and DK#2 is running perfectly. DK#1 just showing this on the monitor after not being on for a few weeks: Since all of the games have been off for about a month, my first thought...

It is actually completed...The board would not let me post more than 8 images in the original post, so I had to just link the URLs from the last half of the images. This is the photo of the completed machine:

After making the decision that I needed to add an original Bud Tapper to the collection, the quest for one began sometime in 2010. About a year later, we found one in Portland and knowing these are a fairly rare machine, we instantly packed up the truck and headed out. I had to pay way too much...

Good call! That's almost exactly what is going on with this one. It looks like B/M used something very similar to what you've mentioned. Mylstar sent me a couple photos of another one and here's what we've come up with thus far.

The odd thing is that there is absolutely no groove for an e-Clip on the bar. I ordered an actuator and e-clip from Mylstar as he said this was going to be the solution as well, however the bar on my machine is missing the groove as pictured in the first photo. Did they have an even earlier...

While restoring my fairly early Spy Hunter cab (#3612), I discovered the accelerator would not calibrate correctly, and the speed was not correct in game. After replacing the commonly failed pot with no remedy to the problem, we realized there was something wrong with the accelerator bar itself...

Looking for the L bracket that holds the fan in the bottom of a Paperboy cabinet. If anyone has one they can sell me, please let me know.

I have to replace the springs in my PB controller. I've disassembled the controller right up to the scary part of bangin' those roll pins. If anyone has experience with a PB controller and would like to do a spring replacement in mine, I would be forever grateful! Any help on this one would be...

For a multi-cade CP, I would recommend the Ultimarc Mag-Stik Plus as they are switchable from the top of the panel for quick and easy swaps from 4-way to 8-way in less than 1 second. We just put two of these in a control panel and the joysticks are a dream to play on...

I purchased this machine in non working order and had a guru friend of mine go through it to troubleshoot the issues, got it working and actually replaced the video cable with a brand new one, which did clean up some other video shadowing that was going on, and replaced the monitor but the...

I'm hoping someone may be able to shed some light on a video issue I'm having with my Atari Paperboy. Everything works fine, however, the colors are not accurate, and it has completely lost the ability to produce yellow (yellows are just white, and the first house that is supposed to be orange...
