How much power (Volts and Amps) does a knocker need to produce an arcade quality knock?

[shaker]

 

Hi All; 

 

After asking for opinions on DOF, I decided to install SSF, an upgraded shaker and a knocker. 

 

The shaker and knocker share a 12V 2A power supply.  The shaker works great, but the knocker isn't a knocker: It's a tapper.

 

What do I need to turn my tapper into a knocker? (It's from Spooky Pinball.)

   Just more amps?  (With a 12V power supply, so the knocker could still share the same supply.) 

  Just more volts?   (A 24V or 48V power supply, but still only 2 A.)   

  Both more amps and volts? (If so, what do you recommend?) 

 

Thanks!

Answering my own question:

 

I found that a 24V 2A Power Supply produced a good solid knock with the Spooky Pinball knocker. 

 

Not the loudest compared to real pinball machines, but in the middle of the crowd.

 Did you get the 12 volt or 24 volt spooky pinball knocker?

I was thinking of getting the 24 volt knocker for decent knock sound.

I didn't know there were multiple Spooky Knockers. 

 

I purchased mine from pinballlife.com. 

 

There was only one choice available: 

Product ID: PBL-100-0021-00
Knocker Kit For Spooky Pinball

 

Let me know if you would like me to check the coil for a rating (gauge and windings).
