/diy/ - Do It Yourself

Where is a good place to put volume pots in an audio (tube) amplifier? Input, output, feedback loop, or somewhere inter-stage? I can't really seem to get good results anywhere due to the pot loading the circuit in unusual ways. Should I add a cathode follower or a more conventional emitter follower somewhere?

I'm using a 100k pot with the tap in parallel with a 33k to create a fake log pot as described by
