gm70 power playing in the lowest freq's

I have been playing with my 2 stage parallel feed gm70 amplifier its measured freq response is good im down about 3db 17 cycles but there is not much available power in those ranges 17-25 cycles meaning i can get a few watts at best possibly less

all the parts are up to the task(I think) they measure ok so what is the deciding factor for more power in the 17-25 cycle range?

its clipping on its output at these low freq's and the driver tube is not clipping the waveform

is it the gm70 final? not liking the low freq's?

Thanks for your help
