Hello again to the Group.
I have swapped out the PB-1534 from the working unit to my faulty one which had no SSB Tx?and have resolved the "No-SSB" problem.?So if ever you have no SSB drive (or SSB power output) then you can look carefully at this board.
I will now verify the defective board. Likely a change of the FET's will bring it back to life.
Once diagnosed and repaired, I will advise on my findings.
Regards to you all.?
