As shown in the circuit, I now have a circuit board with FETs 2sk1058 and J162 as the front stage 6N11 and 6n6. I would like to ask if I can directly use the existing three 12AX7B and two 7025 electron tubes instead of 6N11 and 6n6?

Hi There, we don't have the relevant class A audio expertise in house to advise on a potential use here. BR John
