I'm in the process of deciding the specific technique I want to use for coupling out of my upcoming line amp project. The output stage is a choke-loaded CF. My options are to either DC couple it - which will require a servo circuit to monitor and adjust the grid voltage so the cathode is always zero - or simply use an output coupling cap 0.22uF - 1uF. The latter is attractive due to its simplicity, but I haven't done any cap testing in a long while. This is a scratch build, so physical size of the caps isn't too important. I can use teflon, PIO, etc. Can someone recommend a favorite coupling cap in this general value range based on recent testing (auditions)?
