572b tubes are typically run at around 2400 volts and 250 ma per tube.  Depending on the type of PS the output voltage of the HV transformer should be:

Around 3400 vac for a full wave CT with capacitor input filter
Around 1700 vac for a full wave bridge with capacitor input filter
Around 900 vac for a voltage doubler

The 160-10 is a lower voltage amp as some actually shipped with 811's. It should be 2000 or less on that amp.
