Quoted from BorgDog:

Which is the correct shooter rod for these? I didn't know they made a shorter barrel spring, thanks for that one.

i could not find the right replacement for the shooter rod, ended up going with a Gottlieb that is pretty much the same leght though the C-Clip slots is further from the tip than the Stern's. Anyone has a better option?

my nine ball has no lockdown bar. Do classic sterns have a specific style?

Yes sir
Often difficult to locate too.

Quoted from woody76:

this has been discussed at length. Data east is a known replacement if you can't find an original. Check pinball life.
I bet you can have it sand blasted, then sand in the metal grain to look like original.
If it's made of standard steel, you'll need to spray with clear so it doesn't rust.

There are two types:
Pins through Hot Hand had a button to insert in the receiver.
Pins Meteor forward used slots to fit in the receiver. I can post a picture of what you’re looking for when I get home.

Gott_Lieb Usually has some for sale on his site but it looks like he’s out. Pm him and too-many-pins to see if they can locate one for you. https://www.jtamusements.com/store/

Quoted from RC_like_the_cola:

Hey folks, anyone have a couple used Stern flipper buttons? The white ones (off white or cream at this point in their old age). I have a game that came with one correct and one replacement gottlieb button, so I wanna replace the gottlieb with the correct button.
Thanks,
RC

I have some, but new ones are not all that much. And you still have to pay shipping.

I'm the weirdo that would prefer an aged original over a new set. Shoot me a pm and I'll happily buy a used original or a few from you.

Quoted from Flynnyfalcon:

Adding post to this thread (from Quicksilver members thread) for more potential eyes.
I’m half way through my full restoration and need to order my last (hopefully) batch of spare parts. I’m struggling to find the part numbers however. Can anyone help?
Flipper Cabinet Switches
Flipper Bats
Flipper bushings
Coil Sleeves - How do you determine? (no listing online anywhere for these)
Correct plunger spring (internal and external)
The long thin (carriage) bolt at the front of the side rails (pretty sure used for earthing)
Is there a better resource than the manual for parts as it’s pretty light on. Thanks

May be able to help out with the flipper bushings and carriage bolts. I bought the wrong bushings for my Meteor, if your flipper baseplate sits off the playfield they will fit. And I should have a couple of spare bolts. PM your number and I will have a look tonight.

I also have a scan of the 1981 parts catalog that I made if anyone needs it.

Several months ago I made a post of how you could swap Bally drop targets into a Stern drop target assembly. I did that today and here are the pics.

Dragonfist is supposed to have red drop targets. You cannot buy red drop targets to fit a Stern. But you can buy red drop targets to fit a Bally. The pics that follow show this swap in action.

Here is Stern drop assembly.

IMG_3273 (resized).JPG

Here are 3 red Bally drops and one white Stern drop. The first thing you will notice is that the Bally drops are rather square up top. They do not have the small side curve as the Stern's do. This is cosmetics. I could make the sides curve like the Stern but I would have to destroy another drop target to make one drop look like a Stern. These are only $3 each. It would cost $27.00 to do this.

IMG_3274 (resized).JPG

Here is close up of the two styles of drops.

1) Bally has a half-moon land just below the target's lower edge. Also, if you look down you will see the boss where the spring attaches is little different.

2) Stern made its lands a little different than Bally. You can see the long skinny piece of plastic extend about 5/8" below the lower edge of the target. And the boss where the spring attaches has less meat around the hole for the spring,.

Keep these two different styles of target lands in mind. Operationally, both styles of lands operate the same. But Sten's style does it better. I'll get to that in a minute.

IMG_3275 (resized).JPG
===============================
The teardown.

This is where I remove a white drop target and swap with a red one.

IMG_3278 (resized).JPG

============================================
The Stern target has a piece of angle bracket that holds the targets in proper position.

IMG_3273 (resized).JPG

From the top and looking down, you can see the land of the targets landed on the angle bracket. This is Stern's way of doing it.
IMG_3279 (resized).JPG

For Bally, with the half-moon land at the bottom of the target, the bracket that holds the target place needs to be reversed.

IMG_3280 (resized).JPG

This is all you need to do to use Bally drops in a Stern assembly. The reverse also holds true. You can install Stern drops in a Bally assembly. And you reverse the bracket where the lands sit.

=======================================
Here is the drop installed with red drops. As mentioned, the profile on the Bally Style drops are different than Stern; That could be fixed with a little bit of work. And while they are red, I don't know how close this red is to the original red.

IMG_3281 (resized).JPG
==========================

This is where the rubber meets the road. How do they work? The answer is: Not worth a shit. NWAS for another new acronym plagued world.

They can be knocked down---with difficulty.

So, as I fairly much thought, I will have to modify the lands. There is just too much plastic contact for the drops to release quickly. For the next time through, I will trim back the half-moon land and make a smaller land area. Perhaps with less material on the land the drops will release a little easier. If that does not work satisfactorily, then I will trash an extra drop target for material to extend the Bally land down lower like the Stern drops are.

So, they work but need improvement. Making the improvement will not be hard to accomplish. I'll be back when I make that mod.

My question is why do the Bally targets so hard to drop? I have noticed any Bally I have played to have lousy working drop targets.

#2913 1 year ago

Hello everyone. I got a Star Gazer, but it will only go through 3 beeps on startup and then nothing. What should I look at? It has an Alltek MPU and Solenoid board. The rectifier was hacked up, but I replaced with a new one and repined all wires with new housings. I changed out the MPU and solenoid board with the same result. What does only 3 beeps tell you?
Thanks

#2914 1 year ago
Quoted from cottonm4:

Their nickname is Bally Bricks

My theory is with the landing spot higher you have less leverage as it’s shorter from the “pivot point”. Sterns is longer from the landing allowing for more leverage. Also the land is skinnier on a stern. Less metal to plastic contact. Less friction. Less force needed to move it off.

My Hot Hand had a slotted receiver and lockdown bar. I have no explanation for it. The pin was not beat up so I assume the lockdown/receiver assembly were original. I was thinking HH was the last MPU-100 game and the slotted lock assembly was a transition to the MPU-200 games but Magic came after Hot Hand, however, I don't know what Magic was outfitted with.

I bet those painted targets, after a few hits, would start looking like some girl's fingernails that needed some new fingernail polish

You worked on a Dragonfist when it was in an arcade? Not too many can make that claim. I wonder how this pin did on location.

You might be missing voltages going to the MPU. Check all the test points with a meter and see if any are missing or significantly off from what is labeled on the board.

Could try this. Corvette America is a good vendor and one restorer tells me it's tougher than most paint:

I'm sure other automotive parts sites have similar stuff.

I have a spare populated playfield in much better shape that someday I’ll restore and clear and pop in replacement of this. Until then this one just came out of the queue and got it running. Cleaning up nice besides the giant wear spot.

I, too, have a nice populated playfield that will someday find it's way into a cabinet. I look forward to playing it with slochar custom ROMs.

They're not as great as some of the later changes.... I think the last time I touched them was sometime in 2012. Spots an Ace in the mid pocket, and of course the changed attract mode.

Probably due for a revisit at some point.

After this first post and my first try with modding Bally drop targets to work with a Stern drop target cage, I found out they just would not drop easily.

So I tried modding the land on the Bally targets by taking some material away from the sides of the land. This was also a bust. They would not drop, either.
Screen Shot 2020-03-28 at 10.13.50 PM (resized).png

So, I used the nuclear option. An old drop target was sacrificed to make land extensions. And success ! I can almost make them drop by blowing on them.

And the red does look fabulous.

I recently got my Stars up and running, and i noticed in the process that there is no high voltage fuse anywhere in the backbox. Games from this generation usually have a big red tag stating "HIGH VOLTAGE 1/4 AMP FUSE", but i see no tag, no fuse, and no evidence that either were ever there to begin with. I'm currently using an SDU that has a 1/4a HV fuse, but i want to install the original SDU that doesn't have a fuse installed on the board nor a place to install one. I'd like to know which wire i should be fusing with the 1/4a HV fuse if anyone can help. Looking over the schematics, I'm unable to come up with it. Thanks!

#2940 1 year ago
Quoted from frunch:

It's the red high voltage wire going to pin 1 at the displays. Fuse the wire before the first display the wire connects to which is probably the player 1 display.

Can you send me pics? Interested if it’s an upgrade over mine. Thanks!

#2944 1 year ago

With all the reproduction stuff available for these games, I can't believe no one has remade the correct Stern drop targets. I know the ones sold by PBResource are not the same and do not play the same as originals. I would think there would be plenty of demand if someone would just remake the originals. I know I would buy them for all my classic Sterns. Nothing looks better on a restored game than new drop targets, but they have to play correctly.

#2945 1 year ago

When I restored my Lightning, I got a set of 9 drops from PBR. They play great on this game. They might brick shot like 5% of the time.

#2946 1 year ago

I have the PBResource drop targets on one of my Stars and they brick all the time.

#2947 1 year ago
Quoted from ita47:

I have been very happy with the play action I get with my PBR drop targets.

What do you mean when you say "correct"? What is the difference between a "correct" drop target and the one that Steve at PBR sells?

I posted 5 original Stern drop targets above. Not in NOS shape by any means, but I have a few if needed.

Hey all. The good news is I just received my full order for the PAA stickers. The bad news is all the cardboard mailers I purchased are still in my office in NYC.

I have every order saved in my inbox, as soon as the smoke clears I’ll reach out to you for payment and get these in the mail. Guessing it’s gonna be a couple months minimum, but rest assured I have enough to cover everybody and as soon as I am in a position to ship you’ll be hearing from me!

Cheers.
