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.

Hi
I had not connected the output transformer for the test.
So all measurements are good from A to L
Sorry I'm a beginner in diy.........:-[:-[:-[
I still have the problem.
I have reviewed my soldering, polarized, no short cut
from what I see.....

when I am 300 ohms all is perfect

at 1200 and  LINE I only have Hum when I touch the gainswitch.
I don't know what to do.

Thanks for your help.

The issue seems to be around RLY3.
You will need to remove the input transformer to check the solder joints.
Follow the instructions here to do so.
