  1. replaced 150k with 15k (resistor)

2+3+4 here we need to solder a capacitor with aproximately 6-7 nF(put one or combine from 2-3 capacitors)

  1. removed 100 nF capacitor
  2. removed 100 pF capacitor

in position 2 it was a 2.8nF capacitor

in pos 3 it was 0.5 nF cap

in pos 4 it was 100 nF cap
