The valve itself helps to get a sound out of push pull which is closer to SE. It's a good blend of compromises, the parallel 300b se doesn't seem to sound right. The market for a SE single 300b can't be ignored either but yes I vote for another look at this type of pp amp.
The voltages are relative, if you are talking about valve amps shut up about voltage.

Paul, thanks for clarifying in another thread what you mean about voltages, I agree with your point in it that offering kits with kV+ HT is dangerous.
I mentioned the 0.56kV HT of the old WAD 300B PP in my Poll options because, to the best of my knowledge, this was the highest voltage ever used on any of the WAD kits. I'm not sure if that is too high these days for liability insurance?!
Valve amplifier kits will always require voltages even if we "shut up" about them, I liked the way that Nick pointed out their direct influence on SE output power in that other thread.
Lots of people want (relatively) lots of Watts from either their preferred topology or their first 'valve amp.'. Awareness of the voltage consequences are better out in the open, especially in a forum that welcomes all from the highly experienced to the novice.
You and I clearly agree that big voltages are dangerous, but where should WD draw the line for a commercial kit: 565v; 750v; 1000v; 320v?
To my mind, the answer to this question will give us all an idea as to the type of kits that can be offered by our new hosts.
