Dear Owners, took delivery of the parts on Saturday and took some time out to fit them today and can report after gutting all the burnt carbon and working the board. New components are in and following Andrews advice set TC1001 to null while checking the other test points.
SWR is 1.02:1 on nearly all bands into a Comet H422 at 3 meters (my test antenna). Working well.
Thanks to everyone who participated and hope I can return the favour in the future.
See the repair which was challenging and used non conductive glue to stick down the core and prevent it moving.

After
I know the board still looks burned but it’s back to good FR4 I assure you. The photo doesn’t do it justice.
73 and hope to catch you all in my log soon.
