Anthony, I think you take the right this in a wrong way. Sure the quality of the coupling caps is important but you truly shall not be worry about it. Make the amp, get comfortable with it and then change the damn cap. It is very simple to do and I am sure you will find zillion caps to experiment with. Do not worry about it for now.  For a full range amp 2uP will be enough. The cap and plate impedance will create low pass filter. You want this filter to be a couple octave under the lower cut off of your transformer. If you get at full power -3dB at let say 18Hz then to cut off for the filter at 7-8 Hz would be sufficient.  With 2uF you will be somewhere there… Do not forget that you can always parallel the caps, to bypass the caps… there is a lot that might be done..  but later….
