RE: Limiting low frequency response of SE amp

assuming the amp has at least 1 coupling cap in it then that is the best place to do it. Simply adding another cap for a filter when chances are there are several of them already in place is not a very well thought out plan of action.

Along those lines the choice of coupling cap and resistor combo is a general balancing act with a choice of compromise related to the lowest frequency of interest. Taking a needed low frequency response of say 2hz out of the picture and moving it up a few decades opens up a number of possibilities for sonic improvements.

If you post the schematic or list the tube compliment and coupling cap / following resistor to ground sizes i'm sure a good solution will become obvious.
