Unless the grid of V1 (ECC83) somehow shorts to HT there is not much  
chance of exposure to internal (DC) supply current for the microphone  
user and the input coupling cap can be upgraded to further improve the  
isolation at DC if you wish.
I see what you mean about the mains and the chassis though, but if  
your preamp has it's chassis tied to ground and the preamp references  
the mains ground for earth leakage protection purposes should there  
not be a decent level of safety provided ?
