Please see attached schematic. Considering the phase dots on the transformer, I'm assuming that in this configuration, the relative phase at the speaker will be the SAME as it is to the grid of the output tube. Am I correct...or will the speaker phase be 180 degrees out from the grid? TIA,

Output is the same phase (polarity) as the PLATE, where the dot is.
Grid is opposite phase (polarity) from both the plate and the output.
A common cathode stage, such as this one, inverts polarity of the input.
Note that phase, as used here, is a misnomer.
Phase varies with frequency in virtually all cases. Polarity does not.
