You can hook up each of the audio transformer windings either way.
Whether the signal polarity is inverted depends on how it is connected.
If you want that circuit to preserve absolute polarity, since the tube inverts,
you would reverse one of the transformer windings so that it inverts also.
The capacitor following the transformer may not be necessary.

With a mono channel the human ear is unlikely to detect out of phase.
Out of phase usually becomes a problem with stereo where the channels are out of phase.
The bass part of the sound cancels out when the speakers are out of phase.
If the sound has poor bass in stereo then its likely one channel is wrong.

You're saying what I was thinking: phase is relative to something, but that's the electrical way to look at the phenomenon. Human hearing works with phase to locate direction and distance, the brain filters out some audible program at request. Some of us have an absolute hearing, detecting phase foolproof.
EMRR: Transformer Volume Control, most of the time a single winding with 24 (or so) taps.

True, but are all TVR autoformers? Mine is anyway
Nope. Several people do make true transformer volume controls. The real question is which one sounds better, a tvc or an avc.
Kay Pirinha,
I believe TVA is a Transformer Volume Control.
When is a Three Letter Acronym not a Three Letter Acronym?
Example: FLA, which is a Four Letter Acronym, a Five Letter Acronym, a Forty Letter Acronym, or a Fifty Letter Acronym.
AMA an Acronym that can be taken as the American Medical Association, or the American Management Association.
NBA refers to both the National Basketball Association and to the National Benevolent Association.
The National Benevolent Association existed decades before the Basketball version.
You can see that I am not a real fan of Acronyms.
