« on: March 14, 2021, 08:43:50 PM »
Hi everyone
I just have a signal on the 300ohms nothing on the 1200 and nothing on the line
I checked my diodes and capacitors polarity and soldering.
I have noticed that the measurements are not good on
G=0V
H=1,07
I=0V
J=OV
K=OV
L=OV
The DC resistance is good
could someone please help me
Thank you.
