At Joseph Esmilla's excellent site - je labs - he shows a 75 ohm 2 watt pot across the filaments of his Simple 45/2A3. The ground is from the wiper. I believe you can do the same with a pair of low value, high watt resistors, again with the cathode resistor and cap taken from the junction between the resistors to ground. Maybe someone else can confirm this - or not. The RCA Tube Application section of their tube characteristics books show the same thing, but without values.
