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)

removed 100 nF capacitor
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

YOU SHOULD HOLD RESPONSIBILITY OF WHAT YOU WILL TRY.

GOOD LUCK!!!!!!
