The 270V is the RMS value of the AC voltage coming out of the power transformer.
If you have not simulated the whole circuit, you will not see the proper voltages.
With no loads on the various points in the power supply, they will all show the same voltage when simulated, as you have found.
The belton tank is the equivalent of an accutronics model 8EA1C1B.
The colors shown for the output transformer are the wires connected to it.
You may find a model number on the output transformer itself, but that will probably not get you anywhere.
For proper simulation of the OT you will probably need some spec like the turns ratio or input and output impedance.
Others here that use spice may have better ideas, I have never used it.
