    Transformer coupled or OTL? You should never run a transformer coupled amp without a load attached btw.

    Transformer coupled, don't run it without a headphone attached, you're hearing an arc being created in the transformers.

    Ok, good to know, I wont do that again.
    Was just playing around with measuring waves with my new cheap digital oscilloscope.

    You can use a load resistor if you plan on doing measurements.

    Output transformers sing with or without load. I would say there will be no arcing. The reason for 'singing' is the magnetostriction and kinda loose construction of airgapped transformer.

    I could hear the difference between the sine waves, square waves, triangle waves, and sawtooth waves, sounded like the actual waves
