If your design will have a CCS at each stage, yes. If it has a staged amplifer load then an appropriate resistor might be better. You will have to decide whether your circuit behaves more like a CCS or more like a resistor when the supply voltage changes.
but it seem i cant put a resistive load on the 2a3, only CCS when using the PSUD2.
anyway, i think just using the CCS on both is close enough for me. i just wanted to confirm what i was doing is correct.
