Re: Output transformer HT connection.
I prefer after the choke, so at the second capacitor, provided the dc-resistance of the choke is low (something like 60 Ohm).
In class AB1 the current consumption at full power is higher than under no-signal condition. Because of this any resistance in the power supply creates some sag, although with music/speech the sag will be low anyway. The dc-resistance of the choke will create some extra sag, but I find the advantage of much less ripple worth it. I know that in push-pull power supply ripple gets cancelled, but only totally when the output valves are exactly matched.
