TR-4C Relative Output

  Am servicing a friends TR-4C and the relative output function (push-pull w. LOAD capacitor) does not indicate RF output although a Bird says "all is fine". There are 3 diodes on the relay  board that are part of this circuit and are virtually impossible to get to unless the board is removed.  Everything else seems OK.  Any ideas before I remove the board to check the diodes?

  Many thanks,  Joe k7mks
