Thank you for your help Andy.
I verify the IC4 these are the voltages.
Pins

1) 9.36v
2) 13.02v
3) 13.02v
4) 0.0v
5) 13.02v
6) 9.57v
7) No pin on board
8) 0.6v

The TR35
TX
USB-LSB-AM had the same results
0.0v 0.07v 0.81v
RX also had the same results
9.0v 12.87v 9.26v

Capacitor C133 - C134 - C135. In good conditions all capacitors were replace at the beginning of the project. I double check all of them to make sure I did not made a mistake switching the connections. they are all good.

The light is green on RX. Red on TX.

––No Yellow light––

When I TX I can see the watts reflecting on the wattmeter. I can hear myself on my other radio. the oscilloscope shows modulation.

I can verily hear noise on the Internal and external speaker.

Thank you for your help!
