: Refers to the vacuum tubes (valves) used for amplification.
: A modern approach by Linear Tube Audio that uses high-frequency carrier waves to mimic a transformer’s impedance matching without the actual iron core. tube tranny free
Removing the transformer addresses several inherent technical limitations found in traditional designs: : Refers to the vacuum tubes (valves) used for amplification
: Common industry slang for a transformer (not to be confused with transistors). tube tranny free
Because tubes naturally operate at high voltages and low currents—while speakers need the opposite—"tranny free" designs are complex to build:
: OTL designs often achieve much wider frequency response, especially in the deep bass and ultra-high frequencies, because they aren't limited by a physical core.
