I can’t find them now either, and scanning through my order didn’t help. But “matrix splitter” can turn one matrix output from a GI bayonet into two or three. The comet team is very responsive via e-mail.

Note two other things from my video: 1) cyan is the wrong choice for the blue row in the institute. Use blue. 2) don’t overdo it with the star post lights. If they’re close to the player and directly visible, they’re a bit much. Consider getting a couple of inline dimmers.

Last thing: I learned the hard way that the bolts that attach the star posts and other fixtures to the t-nuts under the playfield tend to bend over time, and so they can break when you unscrew them. Good to have some of these on hand. I didn’t so I improvised something at Home Depot. I’m sure Marco has ‘em.

Can’t wait to see your results!

Warm whites all the way... beautiful

I'm seriously thinking about sunlight whites. I know the warm whites comes as close as possible to the incandescents. Still I would like a little more brightness without going all the way with the cool whites.

That might be nice. For me, if I make it too bright, The reflection of the back box on the glass becomes too much

I ran into this issue as well. I tweaked/adjusted things and never could get it to clear the wire guide every time... about 50% of the time the ball would get hung up there. So I just bend the wire guide out a hair and with that, problem solved.

I think just the sunlights for the pf. Warm whites for the back box...

Thanks to the suggestion from jhanley I got some help from a buddy with a welder. We filled in the space, ground it flat, then dremeled in a new slot. Earthshaker fault problem fixed!

Wow! Congratulations! He did a great job filling the area.

Great fix, had no idea it could get that worn!!

Having a hard time ordering my Sunlight bulbs from Comet. More often bulbs are sold out and I don't want to pay shipping twice by ordering in batches.
I need these 1smd bulbs for GI. Others like the 2smd are too bright or de NG versions won't fit the holes in the pf because they're slightly bigger in size.

Any one get ball stuck here? Happened twice now lol

Ordered my Ultimate Led Kit at Pinball Bulbs yesterday during their Black Friday offer. Incredibly helpful and fast too. Everything was immediately available.
Great service guys...thanks a lot

And I managed helping them out with completing their custom list by adding leds #555 for the Earthquake Institute

I have an Earthshaker playfield protector from Germany that I am not going to use as I decided to go with a playfield swap instead. Priced well to sell. Will ship within US. Pm me if interested.

I have an original institute ES and the building is always up or down, never half way. As you say when you switch the machine on (from memory) it cycles through down and up.

Sold.

New Earthshaker owner here. I love this game!

Welcome to the club... one of the simplest rulesets in my collection, yet always has that one more game feeling. Great callouts... best shaker integration ever (duh, they don’t call me captain obvious for nothing) and overall wonderful gameplay. It’s taught me how to manage multiball and use flipper staging to get that jackpot!!

Just put my ES up for sale in the market place. Selling the house and no room to keep it Hope it can go to a good home.

As per the unwritten rules of ES ownership... you are required to be asked:

1 - Do you have Whirlwind?
2 - Does the building drop?

No ES owner escapes these questions.

Motor is going bad I believe it uses a CCW Counter Clockwise motor. If the motor is going bad it will at times reverse causing the issue you are having.

Hi all...
I have huge difficulties finding replacement parts as shown in the pic. All metal posts shown broke off their threads so I'm missing all posts circled in red. Is there someone who knows what the part numbers are and maybe even where to get 'em. Can't seem to locate a vendor.

If anyone knows or is willing to order for me with full expenses paid please shoot me a PM.

Posts and bases? Those posts are threaded on both sides and the bases are the same for all of them.

Sand the bottoms of the posts where the threaded part broke off. Drill and tap, then use a matching screw up into the post. Problem solved

Sometimes electronic stores have pcb standoff posts, also hardware stores have them sometimes, the bolt holes or lugs may be different sizes than the originals

I’ve probably got all of this stuff. I’ve got all the parts from two fully populated playfields.
If you can measure the posts needed, I can probably help you out.

1. Is there a hardtop available for this machine?
2. Based off of this one photo, assuming everything you couldn't see was perfect... what would you value this machine at: $1500, $1750, or $2000?

May be joining the club soon. I am evaluating a package deal trade that includes this Earthshaker. As you can see, there is quite a bit of wear on the playfield. Assuming everything worked, it would be really great to play an Earthshaker, even in this condition for just a few months like this before moving it on. Is there a Hardtop available for this game? I couldn't find one on Google. I doubt it would be worth my time and effort to do a full playfield swap on this...

IMG_2162 (resized).jpg

If you plan on only keeping it for a few months then just play it. I did a playfield swap a year ago on mine simply because it's a keeper for me. The one you show looks pretty good (minus the wear spots and colored leds in the backbox) and has a blue display which is awesome. I could see you paying any of those prices too. If you can get it for anything under $2000 I think it would be a steal. I might just be biased since Earthshaker is one of my favorites.

I just noticed that the fault mech is open. It shouldn't be and only opens when you are about to lock a ball. It may not be working.

I shot you a pm

Thanks! Ended up with another trade but Earthshaker is on my list!

This is probably a System 11b generic issue but I recently lost my displays, replaced Fuse F2 on the power supply board and after an hour of play the top display started with this...note the top display.

I'm assuming this is a PS issue...

Reseat the display ribbon cables with the power off.

No such luck

Post a pic of your mpu, focusing on the battery area/above the battery.

Also - did you reseat both ends of the ribbon cable? Try flipping the cable end for end.

Yeah I did, in fact I have a Taxi sitting next to it and here are photos with the corresponding Taxi ribbon cable in the same place. I think I see what y'all are getting that, the ribbon cable being out of place or bad, but cable swap didn't seem to matter and the red line is pin 1 on both connectors.

Joined today. Love this game

How about a pic of the battery area on the mpu (remove the ribbon cable)? Any battery leaks? The circuitry/traces for the displays are in the corrosion zone.

Don't think so.

FWIW the Taxi right next door, sharing the same wall outlet just did this:

Not sure if coincidence or what...I powered the Taxi on and off again and all was well. FWIW this behavior is new to both machines.

Report from today. Flipped on the machine today. Displays look great, however the background music decided to take New Years Eve off. Music test is silent, all other sound FX sound as normal. No error messages..

Any ideas?

Side note: In video games I almost always turn the background music either off or way down low. A pinball with no background music is really not as fun.

Here's some good advice... Replace those shit batteries immediately with some lithium or at LEAST some alkaline batteries! You may not have a battery leakage issue now, but you will eventually, if you continue to use those obsolete-20-years-ago "heavy duty" lead acid batteries!
Once you get them out of there, please dispose of/recycle them responsibly!

Oddly enough I made note of those batteries when I first got the machine a few months ago. I thought "Huh, didn't know GM made AA batteries". Never occurred to me that they'd be anything other than alkaline. Thanks for pointing that out!

Hopefully this helps:

And I'll dogpile on those batteries as well. Get NVRAM and never worry about batteries again.

Thats exactly the problem... I don't have the sizes because I, unknowingly of their 'hard-to-find'ness, threw them out after I depopulated mine and broke of in the process.
Is there still anything You can do? Maybe send me the complete bundle of these posts. I'll then for sure have the correct sizes and in the end some spares.

PM me for details if this is a way you could/would go.

I sent you a pm 18 days ago explaining that all the posts are mixed up in a pile of probably 50 others. I don’t just have a set of Earthshaker specific posts all together. They are all mixed in with many others. I said I had the three smaller post sorted but didn’t know the sizes for the 4 at the back. I would like to and will happily help you out with what you need but I’d like to keep the spares incase I need them. That’s not unreasonable is it?

found my old post pictures from 2003. Unfortunately I didn't hold a ruler up to the posts like I started to on later strips but maybe you can tell based on the relative sizes and known quantities which is which.
