Those inline filters are not on the Type 45's, they are on the Type 26 pairs.
The Type 45 filaments just use Modified Hammond 166M2's the 2.5vct @ 3amp tranny. The secondary's tied directly to the 4pin socket via 12ga Mil spec wire. With the center lead replaced with a piece of 10ga Solid Silver wire and Bypasses and Rk attached and then to ground.
The pairs of Type 26 input tubes filaments use a unmodified Hammond 166Q2 a 2.5vct @ 6amps then a 0.1 ohm 10 watt resistor on each leg of the secondary then to the line filter. That gets me the 1.5XXXvAC at 2.25 amps to drive the 26 Filaments.
I definitely learned a lot on my second build. .... I think one more time and I might get it....Just Right !
Have fun
