I also had a thought that the time domain wasn't stretched enough to show that square wave. But that waveform looks very clean to even suggest there is such underlying square wave. Anyhow, my worry with the square wave is the fundamental 66KHz. F3 wouldn't be a concern. There are plenty of other harmonics besides F3 with considerably amplitude but they are at much higher frequency so they may not be audible.
Without the additional filter cap, I guess the halogen transformer works fine without the additional 120Hz ripple.
What's the amplitude of the 120Hz ripple? And you said the hum pot eliminates that ripple hum?
