[Elecraft] K3 no effective TX on 10MHz bands

I realise that it looks like the soldering iron will have to be busy. 
Perhaps there is a relay that has died?? I would love to know what 
component to investigate further - perhaps relays K4 and K5?
 
I cannot find a layout for the pcb and none seem to have been produced.
 
Any advise most gratefully received. 
 
I operate the rig stand alone so there is no interconnection to other 
equipment excepting my PC, however in SSB the problem persists.
