Web“The “parafeed” (parallel feed) uses a large choke to provide the DC voltage to the anode (of the power tube, bold characters are mine). This choke must be large in value, and provides a relatively high impedance (a good thing) at audio frequencies. The output transformer is capacitively coupled to the anode (of the power tube)… WebAn output transformer. Without getting into the specifics of how an output transformer works, they do more or less what the term implies: they transformer. Hooked up between a tube and a headphone, they convince the tube that it isn’t actually connected to 32 ohms, but that it’s connected to 2,500 ohms (or 5,000 ohms, or 8,000 ohms, etc).
