Hi drsx, i have used zeners attached to the B+ to drop the voltage to the grids and they seem to work ok. Although i believe there is a sonic imprint to using it hence my search for different methods for a G2 supply. But i have not tried the method you describe. Others always mention that high voltage zeners are notoriously noisy so i did not pursue trying any zener more than 21v.
Have you implemented your method in a single ended amp and how does it compare to the dropping resistor, sound wise. cheers,
