Quoted from bobukcat:

Shaker maybe, knocker not really unless they use it in ways we've never seen before. I wouldn't expect it to be firing when I'm in a multiball except maybe one time if I hit a replay. I haven't played a Houdini with the shaker in it so I don't know what triggers it. Since the offer is so good (it's like getting the power supply free if you buy the shaker and knocker kit) I'm going to order all three and see if it makes a difference for me. I don't have the fluctuating line voltage like some others do and my lower catapult accuracy is 98%. The upper one shows it's only at like 75% but I have NEVER seen it miss so I don't know what's causing that number to be so low.

Quoted from mbwalker:

BarryJ,
The power supply upgrade: Will this also address the lower catapult inconsistencies related to line voltage?

Quoted from pinballinreno:

Maybe get a little plug in voltmeter to check the wall power if something changes dramatically.

Quoted from drummermike:

I had 115v the other day. Today I have 116v. What is needed and how do we get it to run Houdini without constant adjustments?

Quoted from pinballinreno:

Barry, I saw a 1000-48 supply on jameco.com, the 750's bigger brother.
Is 750 enough power?
In my PC experience, power supplies lose power over time as they wear.
Would it be better to just get an even bigger supply to future-proof my game?

Quoted from Ericpinballfan:

This is designed as a bridge so to speak.
This power supply will provide another 6 amps of continuous flow.
Thus, yes, more than enough power flow. The game only needed about 3 amps more. In fact this probably overkill adjusting for the shaker as well.
There also would be no need for a variac with this extra power, this would make up for low wall voltage.
This power supply is an amazing fix for the game.
Kudos again to American pinball. This has been in the works since almost April, at least on paper. So this should do the trick.
Shaker motor also not an issue, more than enough power now.

Quoted from pinballinreno:

The new 750 watt power supply will not add power if your wall voltage keeps going low.
For that you need the variac and set it 1.5 volts above your lowest power level.
I set mine to 118.5 volts.
Then I adjusted all the settings in the game.
If the power drops a little the game plays fine. If the power goes up, the extra voltage is shrugged off.
The 750 watt power supply will however give you more power to run more things in the game simultaneously. Like magnets and shakers, without running our of power.
So you need it also.

Quoted from pinballinreno:

I get a 9v drop in voltage form my wall power continuously.
It affects all of my games negatively.
I added variacs to all of my games and finally everything is stable.
Commonly AFMr, WOZ, TH, Houdini affected the most.
Adding an additional 6 amps to Houdini will be amazing!
Even more so would be so add another 20v in series to the flipper circuit.

Quoted from BarryJ:

Eric, We scrapped the add on power supply idea and went with the SMPS for various reasons. This is not a bridge, it is a solution.

Quoted from BarryJ:

The new power supply isn't in addition too. It will take over the 48V duty. It has built in PFC (power factor correction) ie if your input voltage goes down the output corrects itself to stay at 48V.

Quoted from PhantomO:

I have 70s on the upper catapult too, but it almost always makes it, so I think the calculatuon is funky. Sadly, my lower catapult accuracy is mired at 76%.

Quoted from PinMonk:

Just got the notice from AP. New power supplies are available from them for people having issues with coil fade. $150 out of pocket, but they'll let existing customers have a $150 credit for their store to offset this:
September 26, 2018
Our goal at American Pinball is to provide quality games at affordable prices.
As many of you know, some Houdini owners are experiencing weak coils when the incoming AC voltage drops because of external loads placed on the service line. We have incorporated a new 48 Volt Power Supply to offset the effect of low incoming AC voltage on the coils.
We are selling the new Low Voltage Offset Power Supply for $150.00 which includes a switch mode 750-48 power supply, retrofit wire harness, hardware and shipping.
We greatly appreciate our customers and to show this, American Pinball will provide a $150.00 credit* with the purchase of the “Low Voltage Offset Power Supply” to be used either at our online store or towards the purchase of an Oktoberfest “Pinball On Tap” machine.
Purchase the power supply online at

Your Houdini machine needs to be registered prior to the power supply shipping, register your game at

Looks like the power supply upgrade is gone as well!

Quoted from Wmsfan-GAP:

I ordered mine yesterday when I saw the post about it- maybe like 10 min after.
Unfortunately, the knocker wasn't on there at the time, so it looks like I missed that one.....

Quoted from pinballinreno:

Im interested in the knocker, but i havent even heard the software one yet on my game. Its turned on HIGH, but i have never heard it. So maybe it will be implemented more in the next code update.

Quoted from pinballinreno:

Shipping was not included on my order for this.
And no mention of any credits for future orders.
Barry, How do I get the $150 credit?

Quoted from PinMonk:

Were you registered before placing the order?

Quoted from Nepi23:

Can the same power solution be used by customers in EU? Is the free shipping applicable also in case, where delivery should be to EU?

Quoted from Rdoyle1978:

For $150, that’s a steal at twice the price.

Quoted from Yelobird:

Sorry I am having trouble understanding how this is so amazing? You would pay double for the transformer that was Suppose to be in the game you paid for to make it function correctly? Seems like a Steal would have been to send Back the incorrect faulty transformer for the one that should have been there in the first place no?

Quoted from pinballinreno:

I have it at 7 and 8 is too loud.
7.5 would be better, or more increments on the control please.

Quoted from rosh:

You can adjust the amp directly to find that sweet spot, the game volume changes will then be relative to your new volume.

Quoted from PhantomO:

Got 7 letters tonight, but game rebooted before I could start master mode. Then got 7 again, and played the master magi mode. A wild multiball with reversed and inverted flippers.I got what looked like a 20 million or 20,000 jackpot ...

Quoted from pinballinreno:

I'm not sure faulty is the correct term here.
It's more of a performance mod or an upgrade.
My game functions without it.
The existing power supply functions, it's not defective.
Not everyone needs this upgrade.
I however would like increased performance in a couple area's.
You understand mod's right?
Do you give away mod's for free?
For a person who dislikes the game and unloaded it, why do you follow this thread?
You seem like a decent guy, but you're coming off so negative it seems.

Quoted from PhantomO:

A wild multiball with reversed and inverted flippers.I got what looked like a 20 million or 20,000 jackpot, and then time ran out and game reset without saving score. Looking forward to the fix. For me the key to getting 7 letters is mastering the first few combo missions and escapes. Meanwhile, that damn elephant still eludes me.

Quoted from pinballinreno:

Power supply upgrade back in stock !

Quoted from BarryJ:

Yes it will address all low voltage problems.

Quoted from mbwalker:

Ordered! I've been pretty lucky with my line voltage, but I'd rather have a regulated supply anyday. I can't recall when the truck shot missed. But if I can do a better job of centering it up (high to low) - I'm all for it. Would rather have a clean shot to minimize any wear. Sort of like a Cliffy, but a power supply instead.

Quoted from mbwalker:

Thanks Barry,
I should have asked about the EOS mod for the flippers too, sorry about that... Still needed?

Quoted from Rdoyle1978:

Yow, man, it’s just a figure of speech. I think it’s cool how they rolled this out AND GAVE EVERYONE A CREDIT FOR THE EXACT AMOUNT OF THE PART.
