I got good results with a CCS loaded 6AH4 driver but I would not use as an output stage . If I needed a mu=8 Ra 1.6k triode for an output stage , I would go for a triode connected 4P1L .
I think to get any decent linearity out of a 6AH4 output stage , local feedback would be required (OPTX secondary in the cathode circuit) .
