Thanks, you saved me the trouble of measuring it.

However....... 2.31 is still a long way from 9v when it comes to rock
bands and the like

But again, John, that 9V won't do you a bit of good if the
peak to peak clip limit of the MD pre input is 2.31V or
less. I think the PIP is always greater on these devices
than the PtoP rails of the pre.

With a mic like the DS70P, for example, which can be powered
by PIP, no battery box will increase max SPL handling. In
general, the maximum voltage that need be used in a battery
box is a bit above the rails of the device input. Having
said that, however, going to larger voltages can potentially
keep the capsule in a more linear region for those rails and
give less distortion for the same output. That is far from
guaranteed.
