    Spoke with Dave at CG and he sees nothing that should cause damage in that circuit but can’t anticipate the long term effects. Really want to tone down the shaker

    So I’m wondering if anyone has installed one.

    Try a variable wirewound resistor in series with either wire. This one is 50 ohms which is a good start. Start at dead short (as if it wasn't there) and increase resistance until you are happy.

    Run it a bit to make sure it doesn't get too hot, although this shouldn't be a problem as its duty cycle is low.

    See attached picture.

    I installed one of these with a cointaker shaker which was way too powerful and it has fine control for the shake. You can turn it down to a kitten purr.
    This should work fine for MMR shaker too.

    This PWM looks like a good product but the seller has a 95% approval rating which is abysmal IMHO

    I have one on every single SAM game I own. You can fine tune them soooooo good. I set mine up for more or a slow wobble which gives it great shake without rattling the game apart

    More of a nice side to side action

    I ordered 10 from China and paid like 30 bucks shipped on eBay
