I am trying to adjust the wireless controllers of my Midway Dart Wall Game, I see there are adjustable pots? on the board, does anyone know what pot does what adjustment? It is split as in one side is Iggy Player and the other matching side is Hank player, the transmitters work once i try many times, they seem to connect and then will let me play a game but after its game over it take a lot of button pushing to get the next game started and playing? The receiver board is not on the schematic as what adj. what? so before i just start turning pots, i thought i would ask around......

That does not look familiar for bullseye. Search for bullseye remote for my write up. It will take an O-scope to tune them.
 
Looking at your receiver again, it looks to be two boards fabricated into one. Also, I do not see any crystals in any of the two positions. Once you get the proper crystals installed, you can measure an AC voltage on the two larger coils. Hold the trigger button and adjust the slug for maximum amplitude. I do not remember which lug and it would not pertain to this board anyway. An AC voltage should be seen on one of them.
 
There coils and are used to align the Receivers RF path. Similar to how you would do an alignment on a portable am radio or home stereo
Your best bet is to do a conversion to a newer receivers and new remotes that can be soldered into the existing remote boxes after the old unstable xtal controlled 27mhz
transmitters are removed. Worth it. Stable and better range. it is not that hard to do. Cost is under $125 2 fobs two receivers and a wal wart 12 volt supply @ 2 amps.

do -you have a manual for your wall game?
 
AHHHHH!!!! all beyond my knowledge, i self taught on switches coils and most em restoring, still learning, but these ??? I hooked up wired controllers i made and game works, but still want the wireless.. I have manual and schematic for the game.
 
Finding a cheap oscilloscope is worth it to keep the original remotes.
You can keep the original boxes, that the transmitters are in.I am not a fan of playing wall games with key fobs. it's worth replacing the guts, a lot more stable , more range…and if by chance you have a unstable crystal,good luck finding the right one anymore.

Very easy to hookup the wireless part.worth it.

Having antique games requires you to learn new skills to keep them original.

You must not have read my history of repairing these things. I have done all of that and kept a log of it here to help people keep original equipment. If your solution works for you, good. It still is not original.

Those aren't pots. They are IF cans, used for tuning frequencies.

If you are doing this without a scope, well, good luck.

You have to find the output and then you use a non-magnetic diddle stick to adjust the IF pots.

The only parts on that board I'd be concerned with are the large black electrolytic capacitor. Maybe the transistors.

Is there a connector which goes to the top of the board? I only see two wires which I think are the antenna wires (one from each board)

The edge connector is corroded (at the top of the board) and should be cleaned to a shiny appearance using a fiberglass pen. Two pins are exposed (one per side), but the other side of the board has the other connectors. These are very small signals - corrosion like that is resistive, and will turn your power into heat. Clean that first.

I love original ,but i am not going to loose sleep over replacing the guts on a original remote box and receiver, with even some remade stickers for the old
bakelight boxes. Stable , reliable and make the game so much more ffun to play.
I have the equipment and 2way background to. Fix the transmitters and receivers .
More reliable more fun.
