Quoted from Chisel:

I’ve been on an early stern streak it seems. My first was Meteor awhile back which i still have. Next was a Trident. Then in the past 6 months I got a Cheetah (blue cab), Wild Fire, Stars and a Dracula. I need a lockdown bar for my Cheetah, would be great if anyone could help me out with that.

I’m sure that it’s the second one that you need here:

Cheetah is widebody. That bar isn’t.

Good point. Didn’t think of that.

The Data East lockdown bars will work fine. Original Stern lockdowns are basically impossible to find. Use the DE one and pray one day an original will show up

How many widebody data east game were there? GNR, WWF and BF? Better grab this last one floating around there.....

I don't think the widebody DE bars fit classic Stern games. The bar is a different length and the "tangs" are placed in different positions.

It won't if the tangs are in the wrong spot. The lockdown receiver on classic stern tab style lockdowns is the same between the widebody and narrow body it's just mounted in the middle and they made the lockdown bars by cutting regular bars up on an offset and joining them together.

Pinball Life shows both the narrow and wide body lock down bars. Only one receiver is shown.

Since Data East just Gary Stern riding with a new name I’m betting the same economic manufacturing practices that drove Stern carried over to DE.

What worked for Stern was still good. Why reinvent the wheel?

I’m betting the wide DE bar will fit. It just will be painted black and not shiny stainless.

Quoted from slochar:

Trident does not have enough solenoid circuits to run a chime box a custom driver board would have to be manufactured and added to j5.
Dracula and Wild Fyre conveniently are the exact same romset and do have space for a chime box. Can you test the roms once written? You'd wire up the chime box in the exact same configuration as Stars. Nugent will be under test soon but if you can test that as well too.
Currently Nugent just replaces the sounds with the chimes - there's no start up chime tune or anything yet. That can be added later.

And, for anyone interested, here is a very (very) short video of Nugent with chimes - https://photos.app.goo.gl/BKi7xL9qng28HYya6. Never heard Nugent with an SB-100 sound board, but I know it's just as awful as every other M-100 game. Thanks again for making this happen, Scott!

We went over this before. I bought the Data East receiver off a WWE and I had a classic Stern widebody lockdown bar for Orbitor 1 and my data East bars were interchangeable. Literally scroll up just a few posts.
They are identical and they will fit. Cotton made a HUGE post about how they are all interchangeable. I even emailed Pinball Life and explained it fits perfectly, I guess Terry either doesn’t believe me or hasn’t updated the site since then. They DO work. Trust me because I literally just bought them and they’re all interchangeable

It is strange. All Terry has to do is walk out to his inventory, pull one wide body lock bar, one narrow body lock bar, and the one style of receiver that he has in stock and verify the info you passed back to him.

I have reread the Pinball Life link and the DE wide body lock bar is/was made by cutting up 2 standard lock bars and spot welding then to the part that mates to the receiver. This is the exact same way the Stern wide body bars were made. There is no way DE went to expense to conjure up some new fangled way to attach a wide body lock bar.

If Terry won't make a move after you showed him the way, then there is no point in me contacting him.

What his site does say is that there are LIMITED QUANTITIES of both the primo wide body bar and the 2nd rate wide body bar. So, if you have a Stern wide body pin and need a lockdown bar you might want to add to your inventory. You can always get it chrome plated or powder coated in Silver. You might wait around and get lucky and find an old original Stern wide body lockdown bar but that string has been getting pulled pretty hard of late. They are getting hard to find and the prices are going up.

You are correct that the latching assys. are the same, but the DE widebody bar is shorter. There was a difference, I just couldn't remember what it was. https://photos.app.goo.gl/aMc5AhM5DFPsiQ2R9

I stand corrected. So, if I have this right, you can take a Stern Flight 2000 wide body lock bar and latch it down to a DE wide body. It will be a little long on the ends but can be attached?

But to try and latch a DE wide body bar to a Flight 2000 can not work because the DE wide body is narrower?

So, if you wish to have a new play field glass custom cut for your Stern wide body you cannot use the same play field glass on the DE wide body; The DE will also have to have a glass custom cut to yet another different size.

I assumed that Stern and DE wide body cabinets were the same size. Talk about mistaken assumptions.

I stand corrected. Thanks.

Odd note but I tried switching lockdown bars between my seawitch and my dragonfist and they don't work. Dragon fist works okay on seawitch, but the seawitch one is too narrow for dragonfist by just a hair...it is really weird.

That is just vagaries between cabinets. They were not built with a high degree of precision. Same for lock down bars. You can probably get a small hammer and do some tapping on the ends of the Seawitch bar and knock them out just a little bit to fit the Dragonfist cab.

O.T. but similar... I did a basic repair on a pinball game.
Williams Jackbot. The lady said that she was just talking to
a local neighbor and her husband had just past away ( the original owner of the game )
and the widow did not need the game so she gave it to her, free.

What I meant was it has been a bit rough, made some silly trades and paid probably more than I should, some I did get lucky due to karma, so it's been a hell of a ride, but not easy.

That's part of the fun - played my QS and DF last night - love those games.

Talk to Scott Charles about getting chime code for Lectronamo. He did it for Nugent, which is the same code. Then, just acquire some Stern or Bally chimes. Nugent never sounded better!!!!

Ok, what am I missing here? I keep blowing Q4, for my outhole coil.
I can trip it by grounding the tab on Q4, and it fires nice and strong, so I know the wiring is good as is the coil voltage.
All other coils are working fine.

Last time I replaced Q4, the coil fired 2-3 times during test, and looks like the transistor went dead again now.
Won't fire either in the game or via test mode.

Nothing is shorting out around the outhole, I replaced the old aluminum sleeve with a nylon one just in case.
New diode on the coil, wiring isn't backwards.

Never had this kind of repeated transistor failure before. But I'm also new to the Bally/Stern SDB. So not sure if I'm missing something.

Is Q4 blowing to pieces or just stop functioning?
Did you reflow the print headers at the driver board?
Sometimes you cannot see the hair fractures...
In this case it should be visible.

Measure the Q4 with a multimeter at diode setting and compare with the other transistors.
If this is oke, replace the CA3081 at U1.

I've seen this a few times. Bad diode, or wired backwards. The EMF from the coil winding is blowing the TIP. Hence why you can ground the tab as many times as you like and it works perfectly every time.

Pinfixer is exactly right.

This is what that flyback diode is for. Your coil is an inductor and stores energy in its magnetic field. When it switches off, the field collapses and can cause voltage transients in the switching transistors outside of their specification, destroying them.

That is fantastic! And they said it couldn't be done. Way to go Scott!
Now for the rest of the -100 Sterns that need the chime treatment. =)

#2296 4 years ago

One of the first things I tried was checking/replacing the coil diode.

Here's where things get weird. It actually worked this morning for a brief time. Looks like if I let the whole thing sit for a while, powered off, I'll get a couple shots with that coil before it rapidly loses strength and stops working. Supply voltage and wiring though are both fine as it fires at full strength if I ground the drive transistor.

I think I'm just going to rebuild the whole circuit for that coil on the SDB, from the 3081 on down.

#2297 4 years ago
Quoted from HHaase:

The transistor usually only blows when there's a problem with the diode on the coil preventing the back EMF being blocked, otherwise most other issues should cause the solenoid fuse under the playfield to blow, not the transistor. Check that fuse and make sure someone hasn't overfused it. Should be a 1 amp slow blow. Banded side of the coil diode should be on the yellow wire. Measure the DC resistance of that coil, it should probably be in the 9 - 10 ohm range.

Yep, fuse is fine. Coil is wired correctly. Coil diode has been replaced. Coil ohm's out fine.
All other solenoids are working just fine.

If it sits overnight the outhole will fire fine once or twice, then get super weak, then stop altogether.

Just very odd.

#2299 4 years ago

Looks like one of the previous times Q4 went, it gave U1 a hit. Replaced U1 and CR4, things are working properly now. At least in that area.

Still plenty of work to do and the restoration continues.

I can at least play full games now, with full solenoids and switches.

#2300 4 years ago

Need a little help with a Dracula flipper rebuild.

I just noticed that the switch stack on one flipper appears to have an extra switch (or some kind of EOS i haven't seen yet - this is my first classic Stern). In any case, the tabs on the switch base aren't connected to anything, but there are old solder lumps on the tabs. What is supposed to be happening here?
