   low power rated Rg2 as an extra layer of protection against bias   
   failure. It isn't a good protection measure because after Rg2 fuses   
   open someone has to solder in a new Rg2, and the best form of   
   protection is via active monitoring of idle bias current and a circuit   
   which automatically turns the amp off when Ia dc exceeds 1.5 x idle   
   value for longer than 4 seconds. My website has details.
