Incandescent lamps are not AC or DC, they are RMS value. Which is either AC or DC.
Your figures look fine, but you are better of with the speaker as this will discharge your lytics when you turn it off, as without it B+ does not get to the tubes and the lytics stay charged after turn-off, and to the higher value (possibly even exceeding their WV rating) too!
Your 6.75 V should be 6.3V but this is likely due to your outlet being 120V and not 110V.
I think you are good to go.
