Will the Vaic Valve 30B work in the BeePre?

It may have addittional current draw similar to the EML.  You can drop the tube in, then measure the voltage across the two 8 Ohm cathode resistors, looking to see about 5V across each.  If necessary, these resistors can be adjusted to restore this voltage balance.
