Appreciate your insight and advice.
Hard to believe the production of the cabinets and pf's have changed so much over the last 5-6 years that's it's an issue... but I read about it more and more these days as an issue folks are talking about and dealing with. Definitely food for thought on this next purchase, so thank you again.

I updated my patched 1.70 code to work with my MikeD LCD mod. Anyone else have the mod going into the "welcome to hell" video mode on the mod when they fire the cannon. When I load the cannon, right after I fire it it swaps the the hell video and a few seconds after goes into back into the next video for the song I have selected. Any fix for this? Any help would be greatly appreciated.

Played a vault last weekend — the ball trajectory was noticeably changed rolling over the window screw heads a number of times. Obviously never had this happening an original.. something to consider.

From the factory the window on the vault was sunken. Home users and decent operators used a washer to make the window level, which eliminates this. Sounds like that operator may suck.

Mine was perfect out of the box, haven’t had to make any adjustments to the window.

My window was low, except for the one spot where someone at the factory accidentally put two rubber washers under one screw, LOL.. that one spot was quite high. The window came out and the height adjusted easy enough though. In my case, I didn't seem to need any additional metal washers to level out my window. The factory rubber washers were enough, I just had to pay attention to not over tighten the screws and compress the rubber washers too much.

Man, I love this game so far. I can't believe I waited so long to get one.

Me too - such a fun game, but I'm still waiting due to current lack of space and funds. A Premium VE is tops on my wishlist though!

This was at a show - straight from stern. But it wasn’t catching on the window, it was slower rolls over the head of several of the screws. The ball was sinking slightly into the (square?) heads of the screws and that was causing it not to roll straight past.

Installed the dynamite mod today. Looks great. Good work from Beatmaster

** Production years to avoid when buying HUO original (non-Vault) AC/DC Premium? **

Hi.

I'm shopping for a HUO example of this title and wondered if there were production years that I should be wary of.

Metallica, for example, had a run with PF's whose paint would chip off. That kind of thing.

Thanks!

I am unaware of years to avoid. Only problem I know is that the very early ones had a more cloudy window but if I am not mistaking this was only with the LE version and they fixed this prior to the Premium run.

Yeah, a cloudy window to the lower playfield is the only thing I know of to look out for, and that's mostly on the two styles of LE.

Thank you, R and V, for your helpful replies.

It sounds like there are no production years to avoid.

Whew!

** Polishing Underside of Lower PF Window? **

Has any of you ever polished the underside of the Underworld window with, say, Novus I?

My impulse, when addressing acrylic that's less than clear, is to polish it - ideally on both sides. Polishing the top of the window is simple enough, but who has polished the underside while the window is in place in the PF? I mean, once you drop the lower PF, is it easy enough to get in there polish that window? Are there any contra-indications? Like, Don't do that because...?

Thanks.

I haven't used novus, but I wiped down and waxed the underside of the window.

Thanks, YZ, for your reply.

** Mods in Order of Importance? **

I'd love to hear from Premium owners just what mods they consider "must-haves" on their pins.

I take the need for a powered subwoofer for granted.

But what else?

I see the clear cross-over ramp is popular. I don't like additional action figures on the PF particularly, but I do love additional light-show enhancements.

Anyway, a list of your personal favorites would be super helpful!

Thanks.

Pretty sure the problem is with the clear itself. There are some videos showing how you can use heat to clear the clear, but given that there's acrylic underneath, I haven't grown the balls large enough to try it.

Color DMD, speaker lights, and the LED lightning bolts. That's it.

** Pinstadium Lights: Do They Succeed/Shine in AC/DC? **

Does any of you have a set of Pinstadium lights in your AC/DC?

If so, how would rate their success on this particular playfield? I happen to think they look best on games with *fewer* clear ramps. For example, they shine in SW and they - ahem! - don't shine in TWD. But that's just my opinion.

Thanks!

P.S. Sorry if I've posted too many queries so quickly. I'm just excited.

I love this pin! I hadn’t played it for a week, because a rubber broke and it was in a pain in the ass spot to fix... Finally replaced it and put up 639,...,... Grand champion... It’s not everyday I get to put my initials in any of my pins anymore haha...

Color DMD, Pinbits Lightening Bolt flashers, lighted band roof mod.

My premium has a cloudy lower playfield window, so they are out there. I actually like it because it diffuses the LEDs a little bit which would otherwise be right in your face. Like others have said, you won't be able to polish it because the clouding is due to a reaction between the plastic used on the window and the clearcoat.

Thanks, V and Boiler, for your replies re: must-have mods.

I thought the lightning-bolt flashers were stock. Did they come stock on later runs? It seems like I've never seen an AC/DC Premium without them.

Yes, with novus 2.
Note the difference in the window lace reflection

Hi, Toads.

Wow!

Helpful photo!

Does the polished window become clearer or just polished? I mean, if the acrylic opacifies, no amount of polishing would help, correct? If the polishing *does* help, then perhaps much of the perceived clouding of the window can actually be polished out, etc.

Thanks for your time!

The lightning bolts are stock, but from the factory they just have an incandescent bulb behind them that goes off in the wimpiest way possible. The LED mod ones light up with LEDs all over the fact of the bolts as you would expect.

It will only help if the under side is scratched up. If it's cloudy that is on the top from the clear. Big thing to note though when looking at used games. Is the window cloudy or just dirty. Some owners are afraid to take the lower PF off and don't clean there. It's super easy to do and takes all of 5 mins but it can look intimidating. I take mine off every couple hundred of plays. By that time it does have a light coating of pinball dust already there.

When buying used you should be OK with a prem as very few had a cloudy window but some did so just check it out first. It will be obvious.

For mods:
- External sub
- Bass drum covers for the diverter coils
- Pinbits Lightening bolt flashers (their are flashers behind the stock plastics but they aren't great)
- Red apron with the interactive lights that integrate with the canon flasher. Makes a cool strobe effect when the cannon is ready.
- Shaker (some don't like them but I enjoy it on this pin)
- Roof top mod (if you can still find one) as they cover that ugly hole in the back right corner as well as add lighting for the band members
- mantis protectors for the scoops

Thanks, '85Vette, for your help. I'm encouraged to know that the window can be polished without *too* much fuss and that the "clouded" window is limited to the LE's.

Thanks for these suggestions. Don't know what the covers for the diverter coils might be, but I will research it. Kerry at Mantis says he makes no protectors for this playfield, so I wonder: did you mean Cliffy? And what mod maker offers the lighted apron?

To make sure I'm being clear. Their are some premiums with them but they are few and far between. You can't polish out the cloudiness but if you get minor scratches you can polish them out carefully. It's acrylic so all those rules apply.

Thought they were manits protectors. Must be someone else making the same style then. Here is what I got years ago. I just have the two scoops and not the other two. Looks like he sells as a full kit now. I've got thousands of plays on my game with them and no wear at all.

ebay.com link: Stern Pinball ACDC Total Protection Kit

I looked at this eBay kit per your suggestion. It appears to include a protector that mounts behind the drops. Interesting. All the pieces are stainless. I wonder if they're "clangy." Did you have to drill any holes in the top of your PF to install the scoop protectors from this kit?

Oh, and thanks for your message.

Cliffy has them...

Took my lower pf off for a good clean last week. Looks daunting but it's not. A beer for bravery helps. Six or seven plugs, a few screws and the lower pf comes off in five minutes. It's not hard. Mind the plastic devil horns. I have a cloudy LE LTBR which I prefer, it's hell down there and smoky and dusty is ok. Novus 2 works great but some cloudiness remains between the layers.

My TNT targets sometimes go down without even being hit, sometimes just when the ball is placed in shooter lane. Often will register as hit just by shaker motor or randomly.

Also my slings are crazy strong all of the sudden will shoot the ball in the air sometimes over the opposite sling into the drain.

Any thoughts?

No, they mount from the underneath. I don't recall if they fit in existing holes or you make new ones with self tapping wood screws. I believe you make your own.

Hi, Rai.

In my experience with Stern S.A.M.-system pins, there's a setting in the "Adjustments" menu within the main Service Menu where you can set the power of the sling coils to low, medium, or high.

As to your TNT drops that drop without strikes, I don't know a fix offhand, but I would start by raising the playfield and taking a close look at how the bank is sitting in the PF slot. I s'pose there's a chance the bank is sitting too far forward, placing the slightest amount of pressure on the drops. Loosening the anchor screws will allow a small amount of repositioning, but not much. The other thing to note is the fact that the AC/DC playfield gives up a lot of its rigidity with the presence of a giant mid-field hole cut out of it for the Underworld PF. It's not unreasonable to think that even ejecting a ball into your shooter lane will cause a minor tremor of the PF that *could* be enough to trigger a drop target if its bank were in the wrong position.

Sounds like your targets aren't resting enough on the "ledge" piece that holds them up and are therefore essentially set on hair trigger. Ideally, just adjust their position so that they catch more on this ledge. Check to see that the catch edges on these pieces aren't overly worn also. If so, you can sharpen by filing/trimming or just replace if really bad.

Thanks

Just completed.

I got one from another Pinsider but I’m curious what how can I add any additional lighting to that area?

If memory serves me correctly you got one of my versions (red ones).

With the matrix system it's stupid easy now. Their are two GI bulbs behind the band. Just get a matrix kit with the color lights you want, plug it in their and use the double sided tape on the roof mod. To integrate into the flasher you can create a harness to piggy back off that plug. Just need a male and female .093 molex connectors and plugs as well as about 3 feet of wire. Soldier one end to a 12V LED strip of your choice and the other end make a bridge to go in between the factory plug. Or you can use a 12V matrix plug, get a splitter and two LED light strips. One goes in the back and the other in the front so both sides still flash.

Not hard but can be time consuming but with the advent of the comet matrix system it's way easier now.

I just installed a Stern translucent apron in my game and think it would look even better if it was lit. Anyone have any quick instructions of what needs to be done and purchased to tie this into either the cannon or ramp flashers? Thanks!

You just need two 12v 6 SMD pads. One goes on each side of the apron underneith it. Then you just wire them into the harness for the cannon flasher. Can't recall if it's a z connector or molex.

Do yourself a favor and get one more pad (in yellow) and put it in the cannon. You'll thank me later

Thanks! Will these work?

Or these?

Can you show a picture of the LED placement you have in your cannon? That sounds like a great idea!

Either will work. I have the top ones.

Here is a pic of all lights and wiring.

The red and black is the cannon and the added IDC is the apron lights. Now that they have them a frosted 12v strip may be better in the cannon. I may try that.

How did you connect the cannon LED to power? Do you have it tied into a specific bulb/flasher? I have my translucent red apron lit up but I have to check what I have it tied into as I can't remember on my AC/DC if it's pulsing lighting tied into my flipper buttons or if it is tied into some of the flashers....
