    Hi

    I have a question about the driver board, in particular the resistors.
    R19-22 is a 27K 1watt.
    The resistors I received does not have the usual colour codes for resistors  and has the value 27 k printed on the case.
    Is it ok for me to use the above resistors?
    The image I attached is my driver board.ST120 VTA Driver board build. 83acb110
    Thanks

    You are testing all the resistors before you put them in, right?

    Yes. I used a multimeter to check all the resistors and confirm their values. 
    There is only one resistor with this value 27k 1 watt so I assume this must be the resistor for R19-22. 
    Thanks

    yes of course this are fine high quality resistors, otherwise they would not have been supplied with the kit

    Hi

    My OCD is stopping me from making common sense decisions..sorry..
    I reviewed the photos on your website and noticed the boards don’t all have colour coded resistors, which kind of answered my question.
    Thank you for clarifying the situation.
