Your 8 watt transformer is good, the 42s produce 6 watts and you won't be sending maximum volume to the speaker anyway. The 42 output impedance is 7000 so you can use the 6 ohm tap to the speaker, 2 & 5. The 42 cathodes are biased with the candohm but no bypass capacitor which will reduce the power output slightly.
