Tube power supplies & grounding

[Bill Layer]

Hi Doug, All

  My question is this: should the chassis/AC earth
>ground be connected to the DC common/signal ground
>directly, through a small capacitor, or not at all?

There is nothing technically wrong with connecting the signal and AC 
grounds directly, but you may find that it introduces noise. It's not 
unusual to see the two grounds connected via a small value (10-150ohm) 
resistor. I would experiment.
