dezbaz Posted June 2, 2012 Author Share Posted June 2, 2012 Ha! Double checking has revealed 2 x completely missing tracks and 8 missing component ID's I might send this off next week along with the Pot boards Link to comment Share on other sites More sharing options...

dezbaz Posted July 9, 2012 Author Share Posted July 9, 2012 The prototype boards arrived today I am very happy with the quality I snuck in a little Star wars Test Interconnect, to save cost, for testing some of my Star wars boards on the bench :) Some Pics http://www.amazingarcading.com.au/LAI_Proto_01-sm.jpg http://www.amazingarcading.com.au/LAI_Proto_02-sm.jpg Link to comment Share on other sites More sharing options...
dezbaz Posted October 16, 2013 Author Share Posted October 16, 2013 This project started 2 years ago Today I spent 30 mins and started to assemble my prototype Here's some pics so far. Just spending small amounts of time on this here and there (a time consumer) as other projects are finished too http://www.dsbelec.iinet.net.au/LAI_KZ-001-sm.jpg I picked up 4 or 5 chassis in this kind of condition, and am restoring this one first (One or 2 are worse) http://www.dsbelec.iinet.net.au/LAI_KZ-002-sm.jpg Flyback on http://www.dsbelec.iinet.net.au/LAI_KZ-004-sm.jpg Heatsinks and shields on http://www.dsbelec.iinet.net.au/LAI_KZ-003-sm.jpg More to follow . . . I bought all the parts years ago, so I have to track them down in my shed. (I cleaned the shed a few weeks ago, so there is hope . . Link to comment Share on other sites More sharing options...
Johns-Arcade Posted October 17, 2013 Share Posted October 17, 2013 Looking good Dez! I'm looking forward to building one of these myself one day. The job you did on the PCB's is first class! Where did you manage to find new High voltage transformers and the other parts to suit this chassis? I can only imagine that LAI still had some old stock. I see you're using the STK0080 amps, so this is obviously going on a 20" tube? Regards, Johns-Arcade. Link to comment Share on other sites More sharing options...

Hi John This HV transformer was the one you gave to me a few years ago, the other ones I make will re-use the flyback from them I have a few - 4 or 5 more I only have whole chassis' to redo, no scratch builds unfortunately. I have my eye on a sheet metal bender/roller/guillotine as we speak, to make some metalwork up As for the use of the STK0080's, yes this one will be 20", for my battlezone, which sits in a bad state, as it did when picked it up. I have repro side-art for it (Should get that scanned before I apply it actually) I have plans to use STK100's for a 25" Screen too, maybe a Cocktail 25" ??? I bought some STK-040's too (and 50's), maybe for a 12" B&W screen I have (To be used as a test bench) So many plans . . . Link to comment Share on other sites More sharing options...
Johns-Arcade Posted October 17, 2013 Share Posted October 17, 2013 From me, ok, you must have given it a good clean :) Put me down for some metal work when you get your bender/roller/guillotine. I was thinking of using my re-build for my vector test monitor, which will use a 12" B/W tube, so I'll use the STK0040's in mine, with the smaller neck board. By the sounds of it, I see a Battlezone restoration thread soon. Regards, Johns-Arcade. Link to comment Share on other sites More sharing options...

Only some of the metal gets really rusty, so that's what I will remake Is that the same for you? Just the thin "tin" stuff? Link to comment Share on other sites More sharing options...

Yes Dez, I still have chassis I can re-build, and just the thin metal is rusted on mine too. Cheers! Johns-Arcade. Link to comment Share on other sites More sharing options...
dezbaz Posted February 8, 2015 Author Share Posted February 8, 2015 Well, this is more than 3 years in the making since I started, but time is precious. Life gets in the way Here is the progress I made today towards making my trashed battlezone game a reality http://www.dsbelec.iinet.net.au/LAI_KZ-progress-sm.jpg The parts Mike send me years ago are finally getting fitted. Thanks again This PCB has a few errors - Oops. It was early days, and a prototype. I completely forgot to mark a few caps (No cap screen print at all, LOL), and made spacing a little too big on other caps Some of the parts are left off my list too, so there will be updating to do I can say, I seriously doubt I will ever do another run of this PCB again, so John and I will have the only 5 made. I look forward to the day I can turn this on and get a picture (I hope) - - - Updated - - - Hey mike There are 3 caps with a different symbol. http://www.dsbelec.iinet.net.au/LAI-KZ-XYB-Colour-BETTER.jpg Are they NP caps? C202, 203, 204. The cap kit guy sent me regular elect. The old caps have no pos or neg marked. - - - Updated - - - Looks like it's an electrolytic capacitor Link to comment Share on other sites More sharing options...
dezbaz Posted February 14, 2015 Author Share Posted February 14, 2015 This is getting close now I have more parts to order, and a few to figure out (Inductors/caps etc) Note to John: The pinouts for the transistors are correct but the image orientation (Transistor picture on the board) is not. This type of trannie http://www.dsbelec.iinet.net.au/GE3TO92-40.jpg Unfortunately I didn't know that most old pinouts are available in 3 types. Most were ECB, some older alternatives are CBE, and modern alternatives are EBC When the boards were done years ago, all were done as modern EBC, so none line up with original items. If you look at the pic below, all the transistors are on a 45 degree angle (LOL) Also, there are tons of typos, and omitted IDs, and some bits too close to others. Oh well, if it works I am fine with this http://www.dsbelec.iinet.net.au/LAI_KZ-progress-02-sm.jpg Link to comment Share on other sites More sharing options...
dezbaz Posted April 19, 2015 Author Share Posted April 19, 2015 5 or 6 years have passed I now have a good diagram to work from.

dezbaz Posted July 28, 2015 Author Share Posted July 28, 2015 This is the hardest board to assemble yet. It's all in 1, it's tight, it's poorly marked (By me) LOL The parts are obsolete, and some were ordered 3 years ago - so buried in the shed. Ahhh The original diagram is illegible, the re-drawn one is imperfect, I have found. At least I can fix it now Still making progress. Fitted more parts today, here's the pic http://www.amazingarcading.com.au/LAI_KZ-Assy-01-sm.jpg I sent my Lunar Lander PCB away to be fixed about a year ago, and just got it back this week, so I need this new chassis to be going in that cab to "look after" the LL PCB so to speak I intend to make 2 more of these 20" ones, one for Battlezone, and one for Asteroids. Then I would like to build a 14" one as well, since the components are slightly different on that one Link to comment Share on other sites More sharing options...

Great to see you getting back to this one, who would have thought these would be reproduced. When do you expect to fire it up Dez? Regards, Johns-Arcade.

Yes mate, that chassis in there is presently showing 1/2 screen. Love them vectors :rolleyes If you need a correct diagram, here is the latest. http://www.dsbelec.iinet.net.au/LAI-KZ-XY-Schematic_2015_DB_Rev-01.jpg Them pots we were talking about are R511B & R611B on that diagram Will get the pic of the pots in a few mins (On the old chassis) - - - Updated - - - The pots are here This is an easier to get to board, but has the same mods http://www.amazingarcading.com.au/Pots-LAI-sm.jpg Link to comment Share on other sites More sharing options...
Johns-Arcade Posted July 28, 2015 Share Posted July 28, 2015 Yes mate, that chassis in there is presently showing 1/2 screen. Love them vectors :rolleyes Horizontal or vertical missing? Sounds like one of the STK0080's has failed, or associated drive circuits. Them pots we were talking about are R511B & R611B on that diagram Seeing your picture has reminded me of this mod, and I have seen a few of these LAI chassis with this done, but from memory if was only on the 20" model.

I think it only exists on my 20" ones. Any ideas on what it actually adjusted? On this repro PCB,looks like I added spots for the pots in series.
