Skushino, from what you say I presume you use two pair of ML2, right? Yes, what you say is correct but if I were you then I would not introduce an addition caps to signal path. In my view the best scenario for high path would be to minimize the coupling cap between the stages. Figure out the stage impedance and calculate the new cap that would roll the whole amp at 70hz. It is very simple to attach it to the existing cap – juts clip one lead of the current cap and parallel it with the new smaller cap. For the low path you might go for coil but it will be large and you need to shield it. It is much better to go for cap to ground, sort of subtraction filter. An alternative would be to run the filter in the ML2’s feedback. Lamm run global feedback to the cathode of the input stage. If you contra-filter the feedback then you can get the same desirable result.
