Nice work. Great to see more lady owners. I love Sure Shot. Ed knew how to design simple and yet very challenging pinballs.

Well a call today had me going to repair a Williams" Space Mission" This evening. Game not played for 9 years, First thing check steppers in the back box.
Player unit seized up , took some singer oil and working to free up , Re-solder wire on to one coil . then free up the second stepper ( Credit unit ) Both units i made sure switches opened or closed as they should do and cleaned the wipers and contact rivets,
A quick check of the switches , see them all move as they should.
Now lift the playfield and check all the relays on the base board ,all look good , Now service bonus unit and another stepper both mounted below the playfield. Both needed a free up then a clean of the wiper blades and the rivets .
Fix coins switches , all bent up!. Game set to free play . Game now working , Just had to clean switches of the bonus relay to get it to add bonus after ball had drained.
A clean of the playfield and away she went , owner happy took 2 hours ...
Game bit rough overall , showing it age But nice enough to look at and plays well still , fun game with the swinging target, B/G 6 and Playfield about 6 some wood showing from kicker holes ect and minor planking in a small area.

1... Gottlieb "Jungle Queen" . Fixed this game today, A older guy in city beach ,on the coast. Originally from Newcastle NSW, A old surfie and speedway motorcycle racer! .
Okay now to the game. Not too much wrong , Game setting up correct but not firing the ball return coil ,to shoot ball out in to shooter lane.
The BX( Last ball) relay had been pushed down by hand and some switches had come free and were not operating at all.
Switches made good and cleaned up.
Double bonus light not working , a switch on the double bonus relay , also cleaned switches on A B C relays next to the Double Bonus relay .
A few small adjustments on ho;d relays . The guy had said it lost flipper power? so i checked them and made sure all EOS and Flipper Switches worked properly,
A good clean and a few bulbs replaced , BG 8+ PF 6 some planking.
2... Flipper Kits installed in 2 Williams games . the same afternoon i worked at a friends replacing flipper parts on a Demo Man. Twilight Zone.
Faults were 2 EOS swts , both missing contacts and ia wire broken. Both replaced
Now replaced Flipper links ( All flogged and 2 had home made links : (.
Games played a lot better from the work and a good polish up ...

Gottlieb "Solar City"
Fault. Weak flipper. EOS switch not adjusted correctly , Fixed then showed owner how to fix incase it happens again. Game Really nice for its age 8/10...
Bally "Xenon" .
Game was rebooting! But then it stopped all together. Just a flicker the a dull glow on the LED and a hum that sounded not right .
Replaced 5 connectors , New 12v filter cap ,Memory Cap installed, CPU still locked up !@#
The Ram chip turned out to be dead 6810.
That was after unplugging the SB. Bad( Vocalizer) sound board was causing the lock up i think. After i unplugged it , i could get the CPU to flash a few times and then got the CPU to unlock.
The Sound Rom Chips look as baked as a crack pipe smoker!. All the legs looked cooked and a few legs starting or have broken off . Hope to get a set burnt on monday night .
Also new caps diodes etc to go into the Sound Board...
Bally "Kiss" poor old kiss , Not working for about 10 years.. Game needed Connectors, Memory cap installed and a few transistors replaced on the SOL/DRV board some previous soldering work was shorting in a few places.
All connectors on lamp board were cracked . Re- Soldered these and any that needed it , Game works well ...
Game still all original , With manual and the Flyer for the game. even the broken and re-glued bumper caps and plastics.
Faded cab . but nice still to look at , Playfield had loads of ball swirl but again
still looked good for its age with no real bad wear, owner has had the game for around 25 years ... BG very nice though ...

Of course Ralph.. if I don't have some spare then old mate Daniel should. Between the two of us I reckon we could supply most of your needs or at least show you how we've overcome situations with obsolete parts..
selling?? did I hear selling??... my ears have awoken to the sound of sweet music!..LOL

I read selling but I'll i heard was the walls of my shed bursting lol

Update on the Xenon, Sound board fixed, Thanks to Ratbag for burning 1 new sound ROM.
Credit Display Problem:
Not in Sequence with other displays, even in test mode , and only counting to 3 and then back to 1,2,3 1,2,3 etc. !@#
Turns out it was a short on messy soldering on the connectors on the Lamp Driver Board, ( I had to replace 3 Transistors and i wanted to check this board, The other 2 had been checked earlier) Resoldering the connectors on the Lamp Driver this fixed the problem with the Credit Display and a odd Lighting problem it had had...
Game found a new owner he loves it , Actually played the game today and its good fun. But hard to the 2 ball mulitball

It would be awesome to see some pictures of the games you are repairing.
We only really hear about and see the games that all of us collectors have.
It would be cool to see some of these one of machines people have in their homes.
Do you think most people would mind if you took a photo or two after you finish repairing them?

"Meteor" and AC/DC Pro.. today not much wrong , But wait! Just a few switches not working , was the connector . one transistor replaced for a feature lamp , and adjusted a few switches , IE slingshot and a few target switches...
But F my Dog there is a hole burnt RIGHT through the solenoid board and wires coming from behind it to what looked like a automotive connector cover in insulation tape , Hackery 101. If i go back i will photo it .I cant believe it was still working , i didnt want to look behind the board to see , I did show the owner the problem ...
Also the usual wires all soldered on to the rectifier board connector pins and a few other small hacks , Game going again , but the game really did need some time spent fixing all the old "Fixes" that have been made in the past , It would need a full day to sort it all out i would say essp the solenoid Re-wiring and the connectors for the Rectifier Board ...
But game apart from all that , it was in good nic Playfield had full mylar all good plastics and looked mostly original, Aussie made game (LAI)
Still red in the Backglass and no crazing.
AC/DC pro, just a service , few lights etc , a few switch errors , fixed , and a clean up . Same house as the "Meteor" pinball...

"looked like a automotive connector cover in insulation tape , Hackery 101.Also the usual wires all soldered on to the rectifier board connector pin"
Sounds like the same guy that did my Gilligans? Still working so I aint touching it yet!

"Sounds like same guy that did my Gilligans?" lol
I vote for pics too if u get some customers that don't mind - but if not then keep the great repair stories coming anyway. You've got to wonder if at some point the Meteor hack was close to setting the machine on fire *.*

Worked on a Bally " Dolly Parton " on sat . No pics unfor #@#
Another service and fix , No Controlled lights and 2 coils not working.
. The coils problem ended up being a bad 6820 PIA chip on the MPU. After much searching! ( altek replacement already installed in the game ) This chip handles the momentary solenoid data . Coils fixed!
Now the Controlled lamps? No power at test point? What to do , All bridges tested good, i like to test them all anyway , but this problem was with the Diodes .
New Diodes had been soldered on to old legs!! , De-soldered these properly and replaced the Power Supply's 4 x 4007 diodes that the Controlled lamps power goes through . Had had some work previous ( Shoddy See above ) and re-soldered some connectors etc on the power supply, Also tweaked the fuse clips , they tend to lose the tension. Lamps fixed! .
Fitted new 12v filter cap to SDU , Had the original still , This needs to be done on most of the Bally/Stern games i repair .
Game in great condition ,gave it a good clean , some new rubbers , a new shiny ball! Tightened up a loose flipper shaft. Got all the lamps going again GI's and all the controlled lamps . Game is being used the next Saturday night for a 18th , So will check up and see if its all good still during the week ...
