Default Apology.


When I said "bypass the cathode resistor" I had misread your value of 10.0 as 100. There is no reason to bypass 10 ohms here.
Sorry for the confusion.

One final question regarding this subject. If I use DC on the 300B filament and want to use 2 resistors to connect the ground to the middle of the filaments, is the value of the resistors any important? Can I just use two the same resistors of any value?

Choose something like 2*50 or 2*100 resistors of appropriate wattage.

Making the value too big will have little effect,too small and the heater will be a virtual short.
