uBitx V4 no modulation in SSB #ubitx #v4

Hello everyone
I am new here, I have been using my uBitx for about 2 years. In general, everything was fine until you try to build AGC.
Radi has lost a lot of tenderness. I have the impression that the audio track does not work. The transmitter switches on but no signal comes out. The transmitter is rather efficient because in CW the power is correct.
I checked and even replaced Q6, Q70-Q74.
He has no further ideas.
