    Quoted from fxdwg:

    bwaaahahhaaaaa, this is what I was thinking the entire time I was reading this thread. all this talk of knockers... I love all shapes and sizes of knockers... I also love loud knockers and quiet knockers too, they just aren't as much fun... thanks gac, made my morning!

    "What knockers"!
    "Why, thank you doctor".

    Quoted from JethroP:

    Still doesn't explain to me why DC vs AC for louder knocker. I think I get what Tim Arnold is saying...make sure the assembly is tight to the cabinet, and remove 20% of the windings so the coil acts stronger, right? But the OP says convert to DC. That part I don't understand the theory. Is it because the full wave rectified voltage is higher than the AC RMS voltage and therefore produces stronger coil energy?

    Yes.

    Those older Bally knockers are barely audible. It's just how they are I guess.
    They sure made up for it when they started SS games!

    Quoted from JethroP:

    So I have an all original 1966 game, Bazaar, with this "gentle" knocker. Would it be a sin to replace it with a newer style that wakes up the dead? I mean, I get a thrill when I hear a loud knock....like I really won something. Or should I just accept it as the way it was back in 1966?

    You mean you want to subject your "Bazaar" to a knocker enhancement procedure?

    Not my quote. How did that happen?

    Must be a bug but I was able to fix it.

    Thanks, Howard.
