    Is it safe to just remove them? or replacement is needed?

    Well, like I wrote, I wouldn't recommend doing it this way. If you remove the shunts altogether, it will send the card into 2D clocks for sure, since there will be no connection.

    As mentioned, I just wanted a quick and dirty way to test and luckily it worked. Think it's going towards a 2nd year now with the shunt mod.
    Problem with the LM is that you have a lot of small SMDs nearby, and LM is conductive and eats solder. So prep and masking is needed.

    A better way would be to desolder them and apply a silver lacquer or circuit pen to bridge the connection. That way you can undo it and resolder the shunts, should it be needed.

    I would definately avoid your method (sorry to say). If it is safe to remove the resistors, I would connect them with very thin wire. My friend has all the pro tools, he fixes stuff under 500X zoom scope, so technical point of view I see no issue. The big question is it safe to remove all, or smaller replacement is the right way...

    If you just totally disconnect the shunts with nothing the card will be open circuit and won't do anything :p

    You misundestood me.

    1) take off all resistors and short with wire
    2) replace with smaller resistor

    thx

    A 0 resistance will freak it out, so don't solder/wire mod it. A lower resistance shunt then go with half.
