I totally understand.
The question is, will a voltage drop resistor in the filament line for the rectifier tube harm the sonics of the amplifier?
I say it can't if it's not in the B+ path.
The "normal" way to use a DH rectifier tube is to use a filament winding with a CT and use to the CT as the B+ take off point like the example above.
In the example above, a resistor in either leg of the filament winding would be in the B+ path and could cause sonic harm (actually I doubt that it would).
If you don't have or don't use the CT of the filament winding for the B+ take off point then the voltage drop resistor will not be in the B+ path (between the B+ and the audio circuit) so it can't harm the sonics of the amplifier.
I hope this is clear this time.
