Class A to AB ?

johanClass A to AB ?
Hello all  
 
just a little question..  
I know about the problems assosiated with biasing a class AB amp into class A, but what about going the other way?  
I have a little Gibson-GA40-knockoff and I am thinking of increaseing the cathodersistor a little to make it pass over into Class-AB territory( or at least sniffing the border..) for no other reason than convenience when replacing the tubes on the road and far away from my oscilloscope  
 
is there anything I should be aware of, other than crossoverdistortion and possibly a few more watts on that old speaker and output tranformer?  
 
thankfull for any answer..  
 
best regards  
 
Johan
