"However, this differential is shunted by the 5 ohm filament, and as this value is much smaller than the 50 ohm resistor, the actual imbalance of the network as a whole will be much less significant."And if you shunt the 5 ohm filament with a battery? There will be signal current through the battery. :)
In any event, more people than Mark have reported that adding a choke as the last element in a filament supply (L, not LC) results in better sound - a lowering of background grunge as Mark put it. You might theorize that it simply filters out supply noise, but in this case he's using a battery!
Dave's hypothesis is that it helps keep the signal currents where we want them and prevents them from wandering through the filament supply. I don't know if the hypothesis is right or not, but it makes sense and is seems plausible to me.
