I completed a lot of restoration work on my Asteroids cocktail during my Christmas vacation. I had to order some parts because my cocktail needed quite a few items “rebuilt” to make sure they were working properly and ensure it would keep working for years to come. I also ordered some new buttons because the old ones looked terrible.
While I was waiting on the parts I ordered, I worked on some of the internals of the game. It was really clean, except the normal dust. That made this much easier! The first thing I noticed when I heard the game playing during testing was the sound was really weak. I’m more used to the sound of the Upright cabinet, which was really more dynamic. The bass on this one was horrible and tinny (is that a word?). The speaker installed in this cabinet was really tiny, and held on with nails through a vinyl frame. Not a great design. The hole pattern on the speaker cover was the same standard hole pattern used my most smaller speakers in arcade games, so I pulled out the old speaker and replaced it with a better one. I had a really nice, magnetically shielded speaker from an old television I used to own. This speaker sounds MUCH better and more in line with what the game should sound like. It was an amazing difference.

You can see the old speaker laying above. Big difference!
As with most Atari games, the volume control was a tiny potentiometer with no knob. I don’t know if Atari was cost cutting or if these were just easier to turn 30 years ago. Now it’s really hard to turn without a knob. Thankfully I bought a couple about a year ago when I was working on my Centipede, so I put my extra knob on this volume control. Looks great!

They should have shipped with these knobs
Perhaps the dirtiest part in this cabinet, besides the control buttons, was the AC power transformer assembly. These are in all classic Atari cabinets and they always seem to collect all the dirt. This one was in the best shape of any I’ve ever had. I usually have to disassemble them and repaint the main frame, but for this one I only had to clean it up. I ended up disassembling it to better clean it up. I love how these look when cleaned up!
By the time I finished working on the inside of the cabinet, I received my rebuild parts. Since I knew the monitor was not working, I started there. I installed a new cap kit which also included new transistors. This was an easy kit to install. The monitor was not very complicated so the parts were easy to get to. Once I was done I replaced the bad fuses and fired it up. The fuses held and the picture came on! I was very excited that it was such and easy fix.
I knew the game board worked but I wanted to make sure I rebuilt the power board and even replaced some parts on the PCB. Bob Roberts sells cap kits for both boards. They were also easy to install and now everything works great. I can also feel confident that this will work for years to come!

AR board with new caps and transistors
Once I was done with all the board work I decided to do one more repair that is recommended for most Atari games from that era. I wired up secondary power lines directly to the PCB so the wiring harness edge connector wasn’t the only power connection point. Atari games have a history of overheating these connections as the connectors start to get dirty. By bypassing this connection the game will be much more reliable. I also replaced the entire edge connector on the wiring harness to ensure all of the contacts were like new. Lots of crimping but just like new!

I ran the lines from the back of the AR board to the PCB with connectors so the PCB can be removed in the future if necessary
Now that I have the game working perfectly, it’s time to start working on the look of the game. The game was in solid shape but dirty. The glass had several scratches in it and the paint under the glass was peeling. I will need to replace the glass and purchase a new underlay to get this looking new. That will be my next parts order. Arcadeshop.com has a nice reproducion underlay.
The metal legs and glass clips were dirty and rusted. I had a friend at work that has his own powder coating line, and he was able to powder coat them. They came out GREAT! I bought new leg levelers for the legs but the threads don’t seem to match properly. I need to try another set or tap the legs to match the threads on the new levelers.

The next step was to work on the control panels. The painted graphics on the control panel were great and no wear whatsoever. The buttons looked horrible so I swapped them out with new ones. I didn’t like the look or feel of the new buttons, so I decided to clean up the original ones. They turned out pretty good!

The originals look much better and “fit” the panel better
This thing is really coming together. All I need to do is get the new glass and underlay, and this will look brand new! I can’t wait!
