Dave, do you mean PCC83? The ECC83 can be used in 300mA series chains so there's no such thing as a PCC83 that I've ever heard of. Presumably given the context B9G is a typo for B9A.
Not sure about you constant pwoer idea. While it's probably true, it's a big hammer to crack a fairly small nut. Apart from a few small B7G triodes I think all P series valves need more than 6.3V heater. So easy enough to use a variable PSU and meters to see what's happening.
