  I want to change green 1K5 resistor with Caddock MP-930 but it's 2,5W to 30W.Can I use this,or I need just 10W.
  Mills 1K5 is 12W I can't find 10W value,do you have some idea which one to use with Interstage Parallel 300B kit.

  from Pin 1 of the 300B to GND and the other to the 220uF/100V cap

    There should be two 1K5 in parallel to common connected to the 300B. These are the cathode bias resistors and from your description seem like Welwyn W23 (which are in my Kit 1 as well). They are 10W each.
    I've used Mills non-inductive wirewound resistors for cathode bias in other amps and really liked them, and will be trying them in my Kit 1 very soon.

      brilliant!
      
      thanks you very much.
      I miss 4 caps (for PSE) and have to look elsewhere.
