I hope to hear more about people's battery biasing experience since I may go this route.Since battery biasing doesn't take much current (if at all) then any battery should work. The old "super heavy duty" pre-alkaline style is known for sounding good. Cheap too.
Rather than putting the battery in series with the cathode a better solution may be to put it in series with the grid resistor. Also consider using a battery bypass cap of 12uF or so, PIO is nice maybe.
2V 25aH+ lead acid batteries can be obtained fairly cheaply. Check All Electronics, ebay etc. You'll have to build a charger.
